The AstroBox Touch has got me excited: Kickstarter or AstroPrint
So I made a case for a Raspberry Pi (3) and an Adafruit 3.5" TFT in a console style.
The Console consists of 3 parts: The Base, The Body and the Top or screen bezel. I used embedded nuts to bolt the parts together and for mounting the Raspberry Pi. The voids for the nuts are in the STL files, simply pause at the layer height and place the nuts then resume printing.
There are choices for the Base, some are enclosed and some an open frame. Both have options for a 40mm fan. The fan mounts below the Raspberry Pi, but there is an air duct that directs air flow over the top of the Pi as well.
The Body and Top should be rotated 45º to sit flat on your print bed. The BaseFanFrame should also be rotated to sit flat on the print bed for best results on the fan mounting surface.
After building your enclosure, follow this tutorial at Adafruit Learn to get it up and running.
When asked "Select project" choose option #2 and "Configure options manually".
10/18/2017 Added: Revised PiBox, I made the wall with the power plug opening thinner to allow plug to seat better. Title: PiBoxTFTPiBoxPlugFriendly.stl
Added: I converted my SolidEdge part source files for those who would like to modify the parts into STEP (.stp) files which can be opened in a variety of software packages including AutoDesk's FREE Fusion 360.
11/14/2017 Added a Base for a 50mm blower fan with 20x15mm outlet. MUCH better airflow.
I used 0.2mm but 0.1 would be better.
You will need:
(1) Raspberry Pi 2B or 3B
(1) Adafruit 3.5" TFT plus
(12) 2.5mm nuts
(12) 2.5mm Allen head bolts 6-10mm long
(1) 40x10 mm axial fan OR 50mm blower fan with 20x15mm outlet.
(4) 3mm nuts
(4) 3mm bolts
I prefer nylon hardware for the fan, that can easily be snipped off to the desired length.
The Adafruit TFT plus 3.5" screen has mounting tabs on the PCB board. The mounting tab that sits over the Raspberry Pi's USB ports should be broken off for a proper fit. The mounting tabs are perforated for easy removal.
If anyone should ever want to turn the TFT backlight on/off it can be done through SSH at the terminal prompt by copy/paste:
sudo sh -c 'echo "0" > /sys/class/backlight/soc\:backlight/brightness'
to turn off, and:
sudo sh -c 'echo "1" > /sys/class/backlight/soc\:backlight/brightness'
to turn on.
I used Solid Edge ST9 to design this case. I am excited for the AstroBox Touch, which inspired this design.
I use, and love AstroPrint !!!!
