Inspired by scouting merit badges, Atari decides to start a tile wall to celebrate his achievements. To celebrate building his first online course (Arduino For Kooks), he’s going to design a tile based on the Arduino Community Logo–a frenetic jumble of multicolored shapes forming the Arduino “infinity” logo. Since his 3D printer only has one extruder, he decides to paint and assemble the differently colored pieces for a nice, lo-fi aesthetic.
I have a couple of new 3D printers that I need to build OctoPi servers for, so in this video, we’ll walk through how to set up OctoPi and attach it to most 3D printers.
Ever notice how your coffee mugs NEVER fit in the standard cup holder–often leading to catastrophic spills, burnt legs, and general angsty bad days? Is that just me? Fear no more, for I have solved this particular conundrum with a little bit of ingenuity and a healthy dose of 3D printing! Let’s 3D print a solution to this age-old problem of oversized coffee mugs and undersized sofa cupholders!
Anet is one of the many 3D printer manufacturers to come out of the Big Rock Candy Mountain of Shenzhen, China, but they have made a name for themselves by developing high-quality printers at relatively low price points. They still remain relatively unknown in the US, so to help spread the word, they sent me a review unit of their new ET4 FDM printer. In this video, I’ll walk through how to assemble the Anet ET4 3D Printer and highlight a few features that stand out as I put it together.
The Anet ET4 is all-metal FDM 3D printer that made with an industrial grade 32bit motherboard and comes mostly assembled. It supports auto-leveling, resume printing and filament detection and comes with a more stable and compact construction design.
This is a simple friction-fit mount for a clamp-style (Logitech C270 or similar) webcam. The mount fits onto the edge of the glass bed and stabilizes timelapse recordings to the Y-axis for clarity.
Make your 3D printer into a wireless print server by adding a Raspberry Pi and capture timelapse videos with an on-board webcam. What do you want to see me print next?

TRASNCRIPT:
1
00:00:00,030 –> 00:00:04,799
hey folks Atari here I’ve been playing
2
00:00:02,790 –> 00:00:05,580
around with this Robo 3d printer for a
3
00:00:04,799 –> 00:00:07,379
while now
4
00:00:05,580 –> 00:00:10,110
and I think I’ve got the hang of it
5
00:00:07,379 –> 00:00:12,660
finally the thing about 3d printing is
6
00:00:10,110 –> 00:00:14,670
it’s very much a hacker minded hobby
7
00:00:12,660 –> 00:00:17,850
there’s a lot of trial and error
8
00:00:14,670 –> 00:00:20,369
involved in the process and most
9
00:00:17,850 –> 00:00:22,710
consumer grade printers do lack a lot of
10
00:00:20,369 –> 00:00:24,960
the out-of-the-box features got some of
11
00:00:22,710 –> 00:00:27,539
the higher-end printers include which
12
00:00:24,960 –> 00:00:30,300
leads people like me to go ahead and
13
00:00:27,539 –> 00:00:32,750
build their own upgrades what I’ve done
14
00:00:30,300 –> 00:00:36,090
here is I’ve installed a Raspberry Pi
15
00:00:32,750 –> 00:00:39,420
with the octoprint software to make a
16
00:00:36,090 –> 00:00:42,719
self-contained Wi-Fi printer and then I
17
00:00:39,420 –> 00:00:45,809
installed a webcam to capture time-lapse
18
00:00:42,719 –> 00:00:48,510
videos of the print process as well as
19
00:00:45,809 –> 00:00:51,449
some LED lighting for better video
20
00:00:48,510 –> 00:00:53,390
capturing and then I’ve you know kind of
21
00:00:51,449 –> 00:00:57,390
rejiggered the cabling and the filament
22
00:00:53,390 –> 00:00:58,559
feeds so that they’re going to move a
23
00:00:57,390 –> 00:01:01,949
little bit better and they don’t be
24
00:00:58,559 –> 00:01:03,629
caught up in may in the works inside it
25
00:01:01,949 –> 00:01:08,280
just makes for a whole lot better
26
00:01:03,629 –> 00:01:11,310
experience so this video is going to
27
00:01:08,280 –> 00:01:16,350
walk you through the process that I use
28
00:01:11,310 –> 00:01:19,320
to install these physical upgrades but I
29
00:01:16,350 –> 00:01:21,659
will have a link in the doobly-doo and
30
00:01:19,320 –> 00:01:26,150
probably up here in the corner a link to
31
00:01:21,659 –> 00:01:30,600
a full how-to article about about
32
00:01:26,150 –> 00:01:33,479
installing and setting up octoprint on
33
00:01:30,600 –> 00:01:35,100
the Raspberry Pi or octopi as its called
34
00:01:33,479 –> 00:01:38,220
I will put a link to that I’ll have a
35
00:01:35,100 –> 00:01:40,680
full write-up on airborne surfer comm so
36
00:01:38,220 –> 00:01:42,720
you can follow that guide there but
37
00:01:40,680 –> 00:01:46,380
again this is going to walk through the
38
00:01:42,720 –> 00:01:48,509
physical installation and with that with
39
00:01:46,380 –> 00:01:50,579
the write-up on the software that should
40
00:01:48,509 –> 00:01:52,680
get you through a pretty much down the
41
00:01:50,579 –> 00:01:54,840
gist of it the first thing I’m going to
42
00:01:52,680 –> 00:01:56,939
fix is the zip tie loop for the cable
43
00:01:54,840 –> 00:01:58,770
loom having a zip tie here has been
44
00:01:56,939 –> 00:02:01,950
holding the Loom a little too rigidly
45
00:01:58,770 –> 00:02:03,930
and has led to a few failed prints I’ve
46
00:02:01,950 –> 00:02:06,210
already cut the zip ties since removing
47
00:02:03,930 –> 00:02:08,640
the hood and now I need to replace the
48
00:02:06,210 –> 00:02:10,500
mounting point for the zip tire I found
49
00:02:08,640 –> 00:02:13,140
a suitable two piece cable loop on
50
00:02:10,500 –> 00:02:15,480
Thingiverse that holds the Loom in
51
00:02:13,140 –> 00:02:18,240
face while being loose enough to allow
52
00:02:15,480 –> 00:02:20,000
some play in the tension remove the two
53
00:02:18,240 –> 00:02:23,459
screws holding the loop mount in place
54
00:02:20,000 –> 00:02:25,740
then replace it with the base of the
55
00:02:23,459 –> 00:02:29,580
two-piece print hang on to the second
56
00:02:25,740 –> 00:02:31,709
piece for later next thing to do is
57
00:02:29,580 –> 00:02:34,500
install some lighting I picked up the
58
00:02:31,709 –> 00:02:37,680
self-adhesive USB powered LED strip from
59
00:02:34,500 –> 00:02:40,530
Amazon and ran it along the interior of
60
00:02:37,680 –> 00:02:42,630
the hood be sure to start with the USB
61
00:02:40,530 –> 00:02:44,790
plug on the slide with the cable well
62
00:02:42,630 –> 00:02:48,239
this is the same side that the loop
63
00:02:44,790 –> 00:02:51,120
mount is installed now before we put the
64
00:02:48,239 –> 00:02:53,459
hood back on go ahead and unplug the USB
65
00:02:51,120 –> 00:02:56,820
cable and the power cable from the
66
00:02:53,459 –> 00:02:59,130
printer place the hood back onto the
67
00:02:56,820 –> 00:03:02,130
base of the printer with the cable loop
68
00:02:59,130 –> 00:03:04,350
on the same side as the well make sure
69
00:03:02,130 –> 00:03:07,170
all the wiring is tucked inside the hood
70
00:03:04,350 –> 00:03:10,170
before pressing down to properly align
71
00:03:07,170 –> 00:03:14,550
the screw holes then screw the hood
72
00:03:10,170 –> 00:03:17,489
securely in place now gently lift the
73
00:03:14,550 –> 00:03:19,440
printer and set it on its side make sure
74
00:03:17,489 –> 00:03:21,810
to hold on to the print cartridge and
75
00:03:19,440 –> 00:03:24,870
abed as they’re likely to slide around
76
00:03:21,810 –> 00:03:26,790
to install the Raspberry Pi we’re going
77
00:03:24,870 –> 00:03:29,190
to need to siphon some electricity from
78
00:03:26,790 –> 00:03:32,340
the printers power supply specifically
79
00:03:29,190 –> 00:03:40,590
from the AC input coming from the switch
80
00:03:32,340 –> 00:03:43,590
on the back of the unit the power supply
81
00:03:40,590 –> 00:03:44,610
on a robo 3d printer is a tough zombie
82
00:03:43,590 –> 00:03:46,769
to remove
83
00:03:44,610 –> 00:03:50,040
there aren’t any screws or anything it’s
84
00:03:46,769 –> 00:03:53,430
just held in the friction very tightly
85
00:03:50,040 –> 00:03:56,190
as you can see taking quite a bit of
86
00:03:53,430 –> 00:03:58,950
effort to remove I found that shifting
87
00:03:56,190 –> 00:04:01,380
it down at an angle back and forth will
88
00:03:58,950 –> 00:04:04,290
garner the quickest results but your
89
00:04:01,380 –> 00:04:06,810
mileage may vary so here are the
90
00:04:04,290 –> 00:04:09,049
terminals these four go into the Arduino
91
00:04:06,810 –> 00:04:13,790
board that controls the printer and
92
00:04:09,049 –> 00:04:19,289
these three are for the AC what dish
93
00:04:13,790 –> 00:04:20,489
blue brown green and yellow OnLive just
94
00:04:19,289 –> 00:04:24,639
get get somebody killed
95
00:04:20,489 –> 00:04:27,039
you see standards exist for a reason
96
00:04:24,639 –> 00:04:29,889
well they exist for many reasons but one
97
00:04:27,039 –> 00:04:33,099
of them is safety international standard
98
00:04:29,889 –> 00:04:35,289
wiring colors are such so that one does
99
00:04:33,099 –> 00:04:37,710
not accidentally connect the wrong
100
00:04:35,289 –> 00:04:41,439
conduct to do the wrong terminal or
101
00:04:37,710 –> 00:04:47,740
worse touch the wrong live conductor
102
00:04:41,439 –> 00:04:50,199
this is wrong this is it’s good right
103
00:04:47,740 –> 00:04:57,370
I mean bed at least the goddamn
104
00:04:50,199 –> 00:04:59,770
terminals are clearly marked anyway
105
00:04:57,370 –> 00:05:02,919
we’re going to need to tap into these
106
00:04:59,770 –> 00:05:05,139
leads to direct power to a standard 110
107
00:05:02,919 –> 00:05:07,180
volt outlet so that we can use an
108
00:05:05,139 –> 00:05:08,379
off-the-shelf power converter to power
109
00:05:07,180 –> 00:05:10,870
the Raspberry Pi
110
00:05:08,379 –> 00:05:14,169
we’ll start by loosening the terminal
111
00:05:10,870 –> 00:05:16,629
screws and removing the leads I picked
112
00:05:14,169 –> 00:05:19,210
up this outlet saver at micro Center for
113
00:05:16,629 –> 00:05:21,310
a couple of dollars essentially it’s a
114
00:05:19,210 –> 00:05:23,919
10 inch long grounded extension cord
115
00:05:21,310 –> 00:05:26,770
take a pair of scissors and cut off the
116
00:05:23,919 –> 00:05:29,589
plug-in then strip away the outer casing
117
00:05:26,770 –> 00:05:32,740
leaving just the outlet end and the
118
00:05:29,589 –> 00:05:35,949
exposed inner wiring at least these
119
00:05:32,740 –> 00:05:37,779
wires are the proper colors so now we
120
00:05:35,949 –> 00:05:40,569
just need to strip the end of the
121
00:05:37,779 –> 00:05:43,330
insulation off of each of the wires so
122
00:05:40,569 –> 00:05:45,940
we can hook them up to the terminal now
123
00:05:43,330 –> 00:05:48,969
remember kids ground is green like grass
124
00:05:45,940 –> 00:05:51,960
on the ground white is neutral because
125
00:05:48,969 –> 00:05:55,719
it’s the neutral color and black is live
126
00:05:51,960 –> 00:05:58,060
because black lives matter anyway
127
00:05:55,719 –> 00:06:01,270
so we reinsert the leads from the switch
128
00:05:58,060 –> 00:06:04,240
into the proper terminal then insert the
129
00:06:01,270 –> 00:06:06,810
new leads from the extension cord into
130
00:06:04,240 –> 00:06:10,599
the appropriate terminals as well and
131
00:06:06,810 –> 00:06:13,270
tighten the retaining screw then simply
132
00:06:10,599 –> 00:06:19,629
reposition the power supply back inside
133
00:06:13,270 –> 00:06:21,789
its retainer with a good shove now we’re
134
00:06:19,629 –> 00:06:23,770
going to need to run a USB cable to
135
00:06:21,789 –> 00:06:26,259
connect the Arduino to the Raspberry Pi
136
00:06:23,770 –> 00:06:28,900
and because the Arduino is mounted so
137
00:06:26,259 –> 00:06:31,330
close to the edge of the base we’re
138
00:06:28,900 –> 00:06:33,789
going to use this right angle USB cable
139
00:06:31,330 –> 00:06:36,279
to make the connection now even with the
140
00:06:33,789 –> 00:06:38,409
low profile of the right angle cable
141
00:06:36,279 –> 00:06:41,469
though we’re going to need to
142
00:06:38,409 –> 00:06:43,569
move the Arduino to plug in the cable so
143
00:06:41,469 –> 00:06:46,179
just remove these three mounting screws
144
00:06:43,569 –> 00:06:48,669
from the Arduino and carefully plug in
145
00:06:46,179 –> 00:06:51,309
the USB cable you can use the existing
146
00:06:48,669 –> 00:06:54,219
wires to hold the new USB cable in place
147
00:06:51,309 –> 00:06:57,009
just be careful not to pull any of the
148
00:06:54,219 –> 00:06:58,959
wires from the Arduino screw the Arduino
149
00:06:57,009 –> 00:06:59,619
back into place and you’re done with
150
00:06:58,959 –> 00:07:03,279
step 2
151
00:06:59,619 –> 00:07:05,769
I found the simple mouth for a Raspberry
152
00:07:03,279 –> 00:07:08,379
Pi on Thingiverse but I also printed if
153
00:07:05,769 –> 00:07:10,959
you get the hole size right you can use
154
00:07:08,379 –> 00:07:12,610
screws to mount the pie in place but I’m
155
00:07:10,959 –> 00:07:15,339
just going to use glue as it’s a little
156
00:07:12,610 –> 00:07:17,439
easier than drilling out the hole apply
157
00:07:15,339 –> 00:07:20,349
the glue to the mount and press the
158
00:07:17,439 –> 00:07:22,419
Raspberry Pi board into place some glue
159
00:07:20,349 –> 00:07:24,279
should come through the holes in the pie
160
00:07:22,419 –> 00:07:26,409
and mushroom over to provide a pretty
161
00:07:24,279 –> 00:07:29,919
good hole clamp some parts together
162
00:07:26,409 –> 00:07:32,110
until the glue sets apply glue along the
163
00:07:29,919 –> 00:07:35,050
perimeter of the mouth and press it into
164
00:07:32,110 –> 00:07:36,669
place on the bottom of the printer make
165
00:07:35,050 –> 00:07:39,779
sure to hold it tightly against the base
166
00:07:36,669 –> 00:07:42,579
of the printer until they do the sex
167
00:07:39,779 –> 00:07:45,789
finally plug the printer into one of the
168
00:07:42,579 –> 00:07:48,279
USB ports on the pie plug one end of a
169
00:07:45,789 –> 00:07:50,529
USB to micro USB cable into the power
170
00:07:48,279 –> 00:07:52,659
port on the Raspberry Pi and the other
171
00:07:50,529 –> 00:07:54,999
end into a wall wart power converter I
172
00:07:52,659 –> 00:07:57,669
think this one up at Tashi station for
173
00:07:54,999 –> 00:07:59,860
about 5 imperial credits just make sure
174
00:07:57,669 –> 00:08:02,709
it’s rated for at least 5 volts and 1
175
00:07:59,860 –> 00:08:04,689
ampere plug your power converter into
176
00:08:02,709 –> 00:08:07,239
your hacked up power outlet from earlier
177
00:08:04,689 –> 00:08:10,839
and now your pie is powered on by the
178
00:08:07,239 –> 00:08:12,759
main switch on the printer again you can
179
00:08:10,839 –> 00:08:16,719
use the existing wiring to hold your new
180
00:08:12,759 –> 00:08:18,579
wiring in place I picked up a short USB
181
00:08:16,719 –> 00:08:20,259
extension cable to connect the lighting
182
00:08:18,579 –> 00:08:24,369
to the PI as well so I just need to
183
00:08:20,259 –> 00:08:26,259
connect that the last USB connection is
184
00:08:24,369 –> 00:08:28,479
made for the webcam which will record
185
00:08:26,259 –> 00:08:30,699
our time-lapse videos for this i’ll
186
00:08:28,479 –> 00:08:32,589
thread the USB cable from the front of
187
00:08:30,699 –> 00:08:34,659
the printer through the cable well to
188
00:08:32,589 –> 00:08:37,350
the underside of the printer and connect
189
00:08:34,659 –> 00:08:40,120
it to the Raspberry Pi
190
00:08:37,350 –> 00:08:41,950
before setting the printer up light go
191
00:08:40,120 –> 00:08:44,500
ahead and insert the cable loom in place
192
00:08:41,950 –> 00:08:46,690
inside the loop installed earlier and
193
00:08:44,500 –> 00:08:51,220
enclose it with the locking piece then
194
00:08:46,690 –> 00:08:52,900
carefully write the printer this is a
195
00:08:51,220 –> 00:08:54,670
widget that I designed myself and
196
00:08:52,900 –> 00:08:56,980
Tinkercad and I’ll put a link to it in
197
00:08:54,670 –> 00:08:58,900
the doobly-do what it does is it clamps
198
00:08:56,980 –> 00:09:01,270
onto the edge of the print bed and
199
00:08:58,900 –> 00:09:03,970
allows you to mount a clamp style webcam
200
00:09:01,270 –> 00:09:06,130
level with the print bed so you can
201
00:09:03,970 –> 00:09:09,490
capture time-lapse video that stabilize
202
00:09:06,130 –> 00:09:11,860
to the y-axis stabilizing one axis is
203
00:09:09,490 –> 00:09:13,480
nice because otherwise motion gets
204
00:09:11,860 –> 00:09:17,410
really messy and you can’t really see
205
00:09:13,480 –> 00:09:19,180
much detail in your printing lastly
206
00:09:17,410 –> 00:09:20,800
we’re going to turn the printer around
207
00:09:19,180 –> 00:09:23,410
to the back so I can install the new
208
00:09:20,800 –> 00:09:25,180
spool holder that I printed this is a
209
00:09:23,410 –> 00:09:27,940
replacement for the stock holder that
210
00:09:25,180 –> 00:09:29,590
hangs off the side of the hood this one
211
00:09:27,940 –> 00:09:31,720
keeps the footprint of the printer a
212
00:09:29,590 –> 00:09:33,700
little smaller and keeps the filament
213
00:09:31,720 –> 00:09:35,620
closer to the center axis of the printer
214
00:09:33,700 –> 00:09:38,470
which helps keep the feed steady
215
00:09:35,620 –> 00:09:40,060
preventing jams and tangles and it just
216
00:09:38,470 –> 00:09:43,290
grips onto the side of the hood and
217
00:09:40,060 –> 00:09:43,290
slides down to lock in place
218
00:09:43,950 –> 00:09:48,580
now if you’ll install these upgrades as
219
00:09:46,690 –> 00:09:50,530
soon as possible after setting up your
220
00:09:48,580 –> 00:09:51,730
logo through the printer you’ll find
221
00:09:50,530 –> 00:09:55,030
that you’re going to get a much better
222
00:09:51,730 –> 00:09:57,370
and much more consistent quality in your
223
00:09:55,030 –> 00:10:01,540
prints and you’ll have a lot fewer
224
00:09:57,370 –> 00:10:03,250
headaches along the way so anyway thanks
225
00:10:01,540 –> 00:10:05,320

meantime uh what would you like to see
230
00:10:12,940 –> 00:10:18,040
me 3d print leave an answer in the
231
00:10:15,220 –> 00:10:20,280
comments below until next time Tallyho
Having a 3D printer at your disposal is pretty amazing, but it can be a pain when you have to keep the printer tethered to your working computer for hours (or even days) while it runs! I was looking for a simple solution to drive my printer while I used my laptop for other purposes (like going to work during the week) when I came across OctoPrint, an open-source 3D printer web interface for controlling and monitoring the printer from a remote computer. The software essentially creates a running web server for the printer and takes the place of printing suites like MatterControl or Repetier, so it does require running on a machine connected to the printer via USB. If you have an old PC gathering dust, you can easily set it up and have a permanent print station. I, however, don’t have the luxury of a lot of space, so I wanted a more portable option that I could pull out when I needed to use it and easily put away. For this, I chose the Raspberry Pi as it is small enough to easily fit into the printer’s form factor, doesn’t require much electricity to run, and has built-in WiFi compatibility. The OctoPrint software even comes as a complete Linux distro optimized for Raspberry Pi called OctoPi.
Out of the box, OctoPi incorporates the LAMP stack for web hosting, a complete OctoPrint installation (including dependencies) for controlling the 3D printer, the mjpg-streamer package for streaming timelapse videos of the print process, and CuraEngine for slicing. This last item, however, is really moot because of the anemic computing power of the Raspberry Pi. I prefer to slice models on my working computer then transfer over the network to OctoPi for printing.
OctoPi is a pretty simple setup with a lot of really good documentation both at the OctoPrint.org site and their GitHub page. To start, make sure you have Etcher installed and simply download the latest stable version from http://octopi.octoprint.org/download (Be sure to grab the md5 file to verify the download as well!). Unzip the downloaded image and burn it to your SD card using Etcher like you would any other RPi image.
If you don’t know how to manage these settings, you might think twice before diving into 3D Printing. Just a thought.
Open the newly burnt SD card as a removable drive in your computer’s file explorer. In the root folder of the SD card, use a text editor to open octopi-network.txt and edit the file as necessary to match your network configuration. Don’t forget to delete the # at the beginning of the appropriate lines or OctoPi will not connect to the network!
Eject the SD card from your computer, pop it into the Raspberry Pi, run a USB cable from the Pi to the printer, and turn on the Pi by plugging it into a power supply. Give the Pi a minute to boot up, and SSH into it from your main computer. The Pi will be located on the network as octopi.local (or an IP address assigned by the router). As usual, the default username is pi and the default password is raspberry.
Change the password using the passwd command, then close your SSH session.
Open a browser on your main computer and point it to octopi.local (or the assigned IP address). The OctoPrint interface will open with the “First-Run Wizard” and prompt you to set up access controls such as username and password. This is specific to OctoPrint and independent of the username and password used to access the Pi via SSH. If you don’t plan on having your printer exposed to the Internet or having anyone else connecting to your network, you may disable access control. I keep it active just in case, so disable at your own risk!
Reboot OctoPi through the menu at the top right of the screen, and you will be all set to print! If you need more help, check out the README section of the GitHub page or drop a comment below!

IF YOU WANT YOUR OWN 2016 TOILET ORNAMENT, LEAVE A COMMENT! IF THERE IS ENOUGH INTEREST, I’LL MAKE A BATCH AND SELL THEM ON ETSY OR SOMETHING.
Forget everything I said about Fry’s versus Micro Center in the last video. I take it all back. Micro Center, hands-down, is forever the first place I go for anything computer-related. Fry’s still has lots of great test equipment and components and other stuff like that, though.
For this experiment, I picked what I thought was an interesting and more complex model from Thingiverse–a toilet. I printed it, and played around with finishing it to see what kind of results I could get.
TRANSCRIPT:
1
00:00:00,000 –> 00:00:04,350
oh holy jesus yeah all that stuff I said
2
00:00:04,350 –> 00:00:07,080
about fry’s versus micro center in the
3
00:00:07,080 –> 00:00:08,130
last video
4
00:00:08,130 –> 00:00:11,099
yeah screw those guys forget i said it
5
00:00:11,099 –> 00:00:13,200
forget everything I said about fry’s this place is
6
00:00:13,200 –> 00:00:15,210
like freaking Christmas man
7
00:00:15,210 –> 00:00:20,880
so I’ve taken my kapton tape and I have
8
00:00:20,880 –> 00:00:22,980
just wrapped it around the end of the
9
00:00:22,980 –> 00:00:25,410
extruder here keep it from getting
10
00:00:25,410 –> 00:00:27,660
gunky and and starting to dribble over
11
00:00:27,660 –> 00:00:30,810
the edges and interfering print also
12
00:00:30,810 –> 00:00:35,370
also changed the color of the filament now
13
00:00:35,370 –> 00:00:37,440
i’ve got this nice little silvery gray
14
00:00:37,440 –> 00:00:41,370
PLA filament in there and we’re going to play with that
15
00:00:41,370 –> 00:00:43,500
a little bit see what happens
16
00:01:36,620 –> 00:01:39,710
as you can see i have 3d printed a
17
00:01:39,710 –> 00:01:48,230
little toilet so so that’s not bad
18
00:01:48,230 –> 00:01:51,140
obviously it’s a little rough i’m going to need to
19
00:01:51,140 –> 00:01:53,990
sand it i might play a little bit
20
00:01:53,990 –> 00:01:57,200
with vapor finishing and see what
21
00:01:57,200 –> 00:02:03,590
happens to it but that’s that so far of course i’ve
22
00:02:03,590 –> 00:02:05,750
taken all the support you saw print
23
00:02:05,750 –> 00:02:08,330
with the support materials and i’ve pulled all that off
24
00:02:08,330 –> 00:02:11,810
now so that makes it a little rough too so that’s where
25
00:02:11,810 –> 00:02:18,110
we are right now start sanding this
26
00:02:18,110 –> 00:02:21,260
120 grit and see what it takes off
27
00:02:21,260 –> 00:02:25,010
so that’s pretty good once-over
28
00:02:25,010 –> 00:02:29,810
with the 120 grit now i’m gonna go
29
00:02:29,810 –> 00:02:34,520
over again with the 320 grit and see
30
00:02:34,520 –> 00:02:37,910
what we do now you can see after a
31
00:02:37,910 –> 00:02:41,270
couple of passes with some sandpaper we
32
00:02:41,270 –> 00:02:45,620
smoothed everything out the bumps and
33
00:02:45,620 –> 00:02:47,930
ridges or kind of a kind of worked out
34
00:02:47,930 –> 00:02:53,390
now if we apply primer and paint we
35
00:02:53,390 –> 00:02:57,890
should have a nice nice even finish at
36
00:02:57,890 –> 00:02:59,060
least that’s the intent
37
00:02:59,060 –> 00:03:01,340
Hey look Harbor Freight’s having yet another
38
00:03:01,340 –> 00:03:03,000
sale
39
00:04:04,010 –> 00:04:07,430
after a bout of painting several coats here
40
00:04:07,430 –> 00:04:13,640
looks pretty decent not
41
00:04:13,640 –> 00:04:18,290
completely like factory finish but it’s
42
00:04:18,290 –> 00:04:20,299
pretty good I could probably sand a
43
00:04:20,299 –> 00:04:22,100
little bit more touch it up with some
44
00:04:22,100 –> 00:04:24,320
brush paint and it’ll look pretty
45
00:04:24,320 –> 00:04:28,220
Skookum but you know that’s that’s it in
46
00:04:28,220 –> 00:04:29,090
a nutshell
47
00:04:29,090 –> 00:04:31,580
so that’s experiment number two down
48
00:04:31,580 –> 00:04:33,650
cool thing about this guy is you see
49
00:04:33,650 –> 00:04:35,180
this little loop right here this is
50
00:04:35,180 –> 00:04:39,680
actually set up to be a sort of a
51
00:04:39,680 –> 00:04:43,430
christmas tree ornament thing so it’s
52
00:04:43,430 –> 00:04:45,889
only highly appropriate that we finish
53
00:04:45,889 –> 00:04:46,970
it
54
00:04:46,970 –> 00:04:50,600
interestingly enough by marking the year
55
00:04:50,600 –> 00:04:53,690
and it would be so appropriate as you
56
00:04:53,690 –> 00:04:56,930
know this is such a shit year is to give
57
00:04:56,930 –> 00:04:59,180
it a toilet ornament
58
00:04:59,180 –> 00:05:01,280
so there we go we’re just gonna mark it
59
00:05:01,280 –> 00:05:09,490
on there
60
00:05:09,490 –> 00:05:12,669
there you have it that’s your 2016
61
00:05:12,669 –> 00:05:14,139
toilet ornament
62
00:05:14,139 –> 00:05:16,870
now i’m gonna go out on a limb here and
63
00:05:16,870 –> 00:05:18,759
say if you want your own toilet ornament
64
00:05:18,759 –> 00:05:20,229
you don’t want to print it yourself i
65
00:05:20,229 –> 00:05:23,860
will gladly print one for you i will
66
00:05:23,860 –> 00:05:26,139
probably throw a link on to something
67
00:05:26,139 –> 00:05:27,699
like etsy or something like that
68
00:05:27,699 –> 00:05:32,680
anyway if you want one drop me a comment
69
00:05:32,680 –> 00:05:35,440
in the doobly-doo and if there are
70
00:05:35,440 –> 00:05:38,020
enough if there is enough interest out
71
00:05:38,020 –> 00:05:41,740
there than not i will quickly open a an
72
00:05:41,740 –> 00:05:43,870
etsy store and get these things a
73
00:05:43,870 –> 00:05:48,759
printed and painted and sent to you and
74
00:05:48,759 –> 00:05:52,300
with all my oh my condolences now again
75
00:05:52,300 –> 00:05:54,220
it wasn’t like completely shitty year
76
00:05:54,220 –> 00:05:55,840
there are some good things that happened
77
00:05:55,840 –> 00:05:57,789
overall on the trend it was kind of down
78
00:05:57,789 –> 00:06:04,509
but there you have it and we’ll see you
79
00:06:04,509 –> 00:06:05,680
again next time
80
00:06:05,680 –> 00:06:09,280
like subscribe tell your friends you on
81
00:06:09,280 –> 00:06:15,490
the motorcycle you two girls and we’ll
82
00:06:15,490 –> 00:06:21,090
see you next time
