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

prusaprinters

<p>This item is a replacement for the bottom of a Geekworm Heavy Duty Aluminum case for RPi4 which mounts to the back on a Prusa MK3/S frame above the electronic box.</p><p>The <a href="https://geekworm.com/products/raspberry-pi-4-heavy-duty-aluminum-passive-cooling-metal-case">Geekworm Case</a> (<a href="https://www.amazon.com/gp/product/B07ZVJDRF3/">Amazon</a>) 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.</p><p>This project replaces the bottom of the case with a near-identical design, adding a mount for the MK3/S frame, combining the thermal performance of the passive cooling aluminum top with the matching integrated mount at the bottom.</p><p>Two screws are required to mount the case to the frame:</p><ul><li>Original version: The total thread depth with frame is 13.2mm, so a M3x12 is best. M3x10 will work in a pinch and M3x14 will stick out a bit but will clear all moving parts.</li><li>Lowered version: The total thread depth with frame is 9.2mm, so a M3x8 is best. M3x6 will work in a pinch and M3x10 will stick out a bit but will clear all moving parts.</li></ul><p><strong>April 2021 Update:</strong> Added a version sitting lower on the frame to clear the excellent <a href="https://www.prusaprinters.org/prints/3267">LED Light Bar Prusa i3 MK2/MK3</a>. The mount uses different screw holes and looks a bit different. The rest is identical.</p><h3>Print instructions</h3><p>The bottom get can get a bit hot so I recommend printing it in PETG or higher temperature material.</p><p>The bottom is designed to print without support at 0.2mm layer height. It should work with other settings.</p>
