Case for dumbpad v1.x

A case for the [dumbpad](https://github.com/imchipwood/dumbpad) 4x4 macro pad with support for up to two rotary encoders.

Originally designed by [Anthony @ customkbd](https://customkbd.com/) (major thanks, Anthony!) with two modifications:

* supports added in the four corners to support PCB during use - without these, the case would flex, particularly when pressing on the encoder
* relief slot added under Pro Micro USB port to avoid putting pressure on cable

Designed for 2x4mm screws - 2x6mm will work if you put rubber feet on the bottom.

### STL Files

* dumbpad_case.stl - base design
* dumbpad_case_emboss.stl - same as base design with "dumbpad" embossed on the back.
