Detailed Information

All of our guides on assembly, updating the firmware, and operation are listed on our Wiki page linked here.

3D Parts

All 3D parts are in the /3d directory on this Github repo in STEP format. A 3D STEP file is provided for accurate reference on the PCB dimensions.

For simpler printing with the smaller bits, we have array components for the buttons and light pipe in the /3d/arrayed parts directory. These are prepared as STL files.
