OctoPi Case Pi 3 or Pi 4

thingiverse

I decided to upgrade my OctoPi setup to a brand-new Raspberry Pi 4. The latest Pi 4 isn't compatible with my previous case, so I had to get a new one. This case can fit either a Pi 3 or Pi 4. There were several things I wanted to achieve with this design. - The case is (mostly) tool-free and screw-free. It snaps together and holds the Pi in place without any screws. Just a couple of M3 bolts and T nuts are needed for mounting to your printer's v-slot or t-slot. - Allowing for a cooling fan on the Pi was another goal. I haven't had any heat issues with my previous setup, but the Pi 4 does run hotter than the Pi 3. The case is somewhat modular, making it possible to fit either a Pi 3 or Pi 4 by printing the corresponding front plate. There are two tops available – one with and one without a GPIO cutout. Three bottoms are also available: one with no mounting holes, one with side mounting holes, and one with bottom mounting holes. Use two of these mounting holes along with 2 x M3 bolts and T nuts to mount the case to an available v-slot or t-slot. The top was designed specifically for a Noctua NF-A4x10 (40mm x 10mm) fan. I may add a more universal fan mount later. For a cleaner design, many of the ports are hidden if they're not typically used in an OctoPi setup. Depending on your printer, supports might be needed for the cutout around the power plug. UPDATE 8-28-2019: After several revisions and the latest test print, I think I've finalized the design and fixed the few minor tweaks that were needed. I've successfully printed and fitted the case. I've uploaded all new "v2" files with the tweaks. I'm still considering making a more universal fan mount, but it needs some work.
