Flatbox: Low profile hitbox-layout fightstick

This repository contains 3D-printable models, PCB design files and code needed to make an arcade controller that looks like this:

There are ten major versions of the Flatbox. They all use Kailh low profile (choc v1) mechanical keyboard switches. The table below lists their main features. See the README for each version for details on how to make them.
