From the project

The arnav-hackpad is a mini-keyboard (or macropad) designed to act as an external number pad with some other cool capabilities, too!

There are 3 parts to the case: the top, the bottom, and the plate. The arnav-hackpad is top-mounted, meaning that the plate is attached to the top part. The design gives an ≈0.3mm printing tolerance. I added a cool design with my name on the plate, which you can see in the plate demo below!
