Modular case for Raspberry Pi 5 + miscellaneous HATs

This is a modular case system for the Raspberry Pi 5 and its various HATs.

(There is also a prototype Rasperry Pi 4 adapter, in case someone wants to try it…)

Comprises a base, a lid and several “spacers”, each one of them with the suitable holes and adaptations for connectors and other features.

The underlying idea is to easily modify the configuration of your “stack” without printing a new case. Just remove or add the appropriate spacer.

Besides the printed parts you will need some screws, length will be different depending on your setup. For the Pimoroni NVMe + Pi 5 + MacArthur combination I have used:

• 4 M3x50 nut and bolt, securing the corners of the case.
• 4 M2,5x8 for attaching the boards stack to the base.
• 4 M4x10 wood screws to attach the fixed holder to a suitable base.

The Pi 5 board and the different HATs are internally connected with the standoff posts usually provided with each one. The bottom standoff is secured to the base with M2,5 screws.

I am very fond of the tools-free release mechanism that allows to remove the whole case from the fixed holding base using only two fingers (I like very much being able to bring it with me without unscrewing).

For the time being I have designed spacers por the Raspberry Pi 5, the Pimoroni NVMe base and the MacArthur HAT. I hope to include other spacers in the future.

In addition to the STLs I have attached the STEP files so it should be easy to adapt my designs to other HATs.

Changelog:

18/3/2025: Flat Bracket V2 with improved adjustment to the holding bracket.

31/3/2025: Added a prototype Raspberry Pi 4 spacer. (I dont have one, so it was mainly guessing from online images. If anyone dares to try it please leave your comments in case some dimension is not correct).
