The file 'The100 Mainboard Holder Mod – Lowered 10mm 3D Printer Model' is (stl) file type, size is 24.2KB.
If like me you've got a heatsink on your 100 Banana/Raspberry Pi setup, then this may help by lowering the electronics tray 10mm, giving just enough extra clearance. Modded from the original part in the100 v1.1 release, fits all the same mountings.
