I made my own Raspberry Pi 4 case because there weren’t any options that fit the cooler I have (Ultra Thin ICE Tower) efficiently.

The design was made in FreeCAD v0.20.2 and printed on my Prusa MK3S+ printer with PolyMaker PLA Pro filament (in black and metallic red). The bottom non-slip foot is self-adhesive EVA foam cut with a Silhouette Cameo 4 cutting machine using SVGs exported from FreeCAD into Inkscape v1.2.2 and sent to the cutter with the inkscape-silhouette plugin v1.28. All software was used on my computer running the current testing version (trixie) of Debian GNU/Linux.
