Case for Raspberry Pi 3B+ with snap-on lid and rail mounts for Creality Ender printers

thingiverse

I made this case to fit the Raspberry Pi 3B+ so that I could use it for OctoPrint. It features a snap on lid and a rail mount. Just pop off the plastic cover on the back of the printer rail and slide it in, as shown in the picture (it may be quite tight so go easy or the mounting bits might snap off, it worked fine for me though). To mount the Pi inside the case you will need four M2.5 x 4mm screws. The holes in the Pi board are M2.5 but you could probably drill them out and make them M3, which might be easier to buy.
