This is a 3D printable shell for DIY a Hitbox. It has 15 buttons, and is modeled in such a way that the entire thing can be printed upside down and assembled without supports. There are built-in supports inside each keycap hole, however should be easy to remove and avoids all the waste regular slicer support could add

Each button slot is meant to fit standard mechanical keyboard switches and wide enough to use these keycaps. https://a.co/d/5hcUzzy

The model was originally designed with this Pi-co board in mind https://www.amazon.com/dp/B0CJM6GNBH?ref=ppx_pop_mob_ap_share However at the time of posting the product says unavailable. I'm not sure if any similar boards can fit so I do encourage remixing.

This model uses only 4 M3 screws to attach the cover.
