Raspberry Pi 4B Mount for Prusa MK3/S (Octopi/Octoprint)

thingiverse

This item is a replacement for the bottom of a Geekworm Heavy Duty Aluminum case for RPi4 which mounts in the back on a Prusa MK3/S frame above the electronic box. The Geekworm Heavy Duty case is a generic, inexpensive aluminum case for the RPi4, meant for passive cooling, with the top of the case contacting 4 chips on the RPi4 board and serving as a big heatsink. This project replaces the bottom of the case with a near-identical design, with an additional mount for the MK3/S frame, combining the thermal performance of the passive cooling aluminum top with the matching integrated mount at the bottom. The bottom get can get a bit hot so I recommend printing it in PETG or higher temperature material. The bottom is designed to print without support at 0.2mm layer height. It should work with other settings. Requires two M3x12 screws for mounting (M3x10 will work if necessary). Revisions: 2020-06-03: Based on RobobTV's Make and feedback on the little nub next to one of the screws, added a 0.8mm lip to the 2 screws closer to the mount to help make a reliable Z-build up around the screws. <A HREF="https://www.amazon.com/gp/product/B07ZVJDRF3/">Geekworm Case</A> <p><A HREF="https://www.amazon.com/gp/product/B07ZVJDRF3/">Amazon</A>
