This is a case system for Raspberry Pis (or same-size SBCs) that I've designed because I wanted to use a Pi case system with the following features:

• Entirely 3D-printable.No additional parts or purchase necessary!
• Expandable!Make as many as you need, then make some more!
• Each bay is independent.Want to swap out a piece in the middle without needing to disturb the other units? You can!

This system is a little larger than I had originally envisioned, but this is so I (or anyone else!) could design bay pieces that would not be possible with a rack system that was sized exclusively for RPi boards, such as a double-height piece that can hold a small display! I'll add that piece when it's ready; still quite rough at the moment.

Please let me know what you think, and please consider posting a make! I'd love to see how these turn out for you.

If interested, FCSTD.zip includes the FreeCAD files; please don't be afraid to modify or add to this project to suit your needs. Please consider sharing your changes if you do!

Important Notes

Project Updates

20/01/20 - Raspberry Pi 4 versions of each bay piece made for the Raspberry Pi 3 have been created. Raspberry Pi 0/0W versions of each Pi 3 bay piece have also been created! (If you want to use the compatible OLED/LCD displays, I recommend soldering GPIO pin headers to your nominated Raspberry Pi 0, [such as these](https://www.jaycar.com.au/40-pin-header-terminal-strip/p/HM3212). Additionally, I've added a small guide pin on the side of each bay piece to assist in mounting a 30x30mm fan.

10/03/19 - Added two single-bay display pieces! Using this 128x32 OLED display, you can now have your Pi2/3B/B+ display text! Also included a piece for Pi 0/0W.

4/3/19 - First Pi display piece has been added, using this 2.8" display. Additionally, replaced photos with current versions of pieces. Most notable with the display piece being the current version.

3/3/19 - Pi 0/0W piece has been added!

Compatibility

The Pi 4 bay pieces have been tested with the following:

•  Raspberry Pi 4B

The standard Pi 3 bay piece has been tested with the following:

• Raspberry Pi 3B
• Raspberry Pi 3B+
• Libre Computer Board (Le Potato)

The Pi 0 piece has been tested with the following:

• Raspberry Pi Zero W

The Pi LCD display bay pieces are designed for use with the following display:

• 2.8" display from Jaycar (also, you will need these to connect the display to your Raspberry Pi. Optional, but would also recommend something to help hold the display in place; I opted for a bit of hot glue personally)Also, ignore Jaycar's advice for setting this display up under Raspbian. Use this guide instead.

The single-bay Pi OLED pieces are designed for use with the following display:

• Adafruit's 128x32 PiOLED display. Once again, will recommend these to actually connect the display to your SBC of choice.

Future Project Goals

Here are my future goals for the project, when I have enough time:

• Display pieces for other small, fitting Pi displays.
• Support for other popular SBCs? (Please let me know what you want to see!)
• Allow for better airflow for fans.
• Allow for front fan space in addition to current side.
• Create a better way to clip the base/supports/top together to help limit potential breakage, and limit any wobble created by building higher than ~3/4 bays.
