This button box provides 13 push buttons, 4 encoders and 4 two way switches which pairs with an Arduino Pro Micro or Arduino Leonardo gives you 33 possible controls you can pass to your computer.

It uses a couple of Arduino Libraries and a button matrix to reduce the number of inputs required.

There are two versions of the lid.  The Inset one prints cleanly and sits nicely inside the base. The Lipped version is a bit more of a printing challenge but has a nice lip that hides the edge of the base.   The recess on the back isn't as deep as the allowance on the box so don't over tighten!  A future improvement would be to add a middle set of bolts on the length for increased stiffness but it works well as is.

The base both 70mm & 100mm Vesa mounts (as found on TVs & Monitors) for flexible mounting.   There is a flat and angled mount included that will allow the box to be attached to extrusion.

There is more information and my other Sim Racing and Printing projects on my website.
