Aluminum Case mount for Raspberry Pi 4B (Octopi/Octoprint)
After struggling with thermal issues on an (otherwise great) 3D-printed plastic mount for my 3B, I decided to switch to a better thermal solution for my new Pi4 (Octoprint).
I was looking at a passively-cooled option and researched the existing solutions including a mount for the whole Flirc case. Eventually, I decided to build a hybrid solution using the top of an aluminum case for cooling and a 3D-printed replacement bottom with the frame mount for the MK3/S.
I ordered a few different aluminum cases and ended up settling for the generic but solid and inexpensive Geekworm Heavy Duty case (Amazon). I recreated a matching bottom and added a mounted feature at the bottom to attach to the back on the MK3/S frame, above the electronics box. I printed the bottom in orange, mostly for the contrasting pictures, but it actually looks very nice, so I am planning to keep it that way.
Did you scan the Geeksworks case or did you manually create the CAD file for the .stl? Nice job, I'm going to make one. Thanks
It's all measured with calipers and then designed from scratch in Fusion 360.
Here are some "mechanical samples" I printed to do fine alignment on edges and holes and test the printing of the fins and screw holes without support.
Impressive work product and thanks for taking the time to document your design effort.
