Raspberry Pi 4 2U rack-mount bracket

A 3D-printed rack mount for Raspberry Pi 4 SBCs using power-over-Ethernet HATs. A simple, tidy solution for making a 2U Raspberry Pi cluster that fits in a standard 19-inch rack. The design is free to download, tweak, and remix, with both the original OpenSCAD files and ready-to-print STL files: https://www.thingiverse.com/thing:407... I also have a version that lets you mount 6 units horizontally in a 1U space:    • Raspberry Pi 4 1U rack-mount bracket   I created these parts from scratch in OpenSCAD, but based my design on this earlier project: https://www.thingiverse.com/thing:160...
