Files

There are three folders: bottom, main-pcb, plate. Inside each of them are a gerbers production folder, and a kicad source folder. Grab the gerber zip files from the gerbers folder.

The clear cover for the components is in the misc folder. There's also a foot you can laser cut to be used with the bottom. Needs M2 brass standoffs or screws to use.
