Raspberry Pi 4 case - Corrected

thingiverse

There was an error in the base plate fixings, which has now been corrected and uploaded along with a new vented case. Raspberry PI 4 Case: Adding a Noctua 40mm 5v fan makes a significant difference, dropping temperatures by 20 degrees while running a stress test. I designed a custom case to hold the fan and protect the Pi 4. Two versions are available for top and bottom, both interchangeable. The main difference between the tops is that one includes a slot for the camera cable, while the other has the fan more centrally positioned. The honeycombed case was an experiment to see if it would aid or hinder cooling. It didn't improve temperatures and actually added 5 degrees during the stress test. I included this design as a personal preference and think it looks better. Both cases are identical except for the mounting lugs. I printed these parts with 20% infill and a .3mm layer height. To simplify the top and Pi4 fixings, two holes were drilled in the top plate to screw through the lid into the base. The other two screw holes hold the Pi directly onto the base. The holes for fixing the main board to the main case are located nearest to the power supply and the diagonal hole closest to the ethernet plug. The screws used are M3, with brass screw inserts intended for the main case but currently using self-tapping screws. M5 mounting lugs were also used. Using PWM and a script to control the fan is highly recommended, regulating its usage based on CPU temperature.
