I found that my Raspberry Pi 4 was overheating when running Octoprint, so I decided to buy a heatsink to solve the problem. The one I bought is really good due to its massive case. However none of the existing cases for the Prusa I3Mk3s+ fit. So I decided to make my own. Designed with heat inserts in mind. The case offers a way of mounting both the Raspberry Pi and the LM2596 ensuring there locked in place.
