* Circuit Design
The schematic and board layout can be found in the [[file:kicad/][kicad]] folder.
* Case
The (incomplete) 3D-printable case is built using OpenSCAD and can be found in
the [[file:openscad/][openscad]] folder. Running make in this directory will gather dimensions from
the KiCAD design and generate STL files using them. The build tool requires
Python 3 with the [[https://pypi.org/project/sexpdata/][sexpdata]] library installed to read the KiCAD files.
The 3D-printable case is built using FreeCAD and can be found in the [[file:freecad/][freecad]]
folder. It is divided into a top and bottom piece. The PCB is affixed using four
M3 threaded inserts and 6mm M3 bolts, the case is assembled using 2 M3 threaded
inserts and 2 10mm M3 bolts.
