This is a set of increased-clearance STEP exports for 3D-printed cases. The "0.1mm" is the baseline from the Rev-03 / CNC-production-run export.
This export is very minimal at the moment: just the clearance gap for the PCB and the screw-hole diameters have been increased.
(Why? The Case.FCStd is broken in FreeCAD v1 (😩) and only works in v0.21.x (previous stable); it'll need some iteration in the future. The clearances are mostly parametric, but there are some baked-in dimensions that came up towards the end of the project that cleaning up, mostly to respect the vertical clearance value.)
