Making a Macro Pad without using Multiplexing. This macro pad has 4 separate layouts with 9 buttons on each for a total of 36 extra buttons. It also has a rotary encoder for volume and play/pause buttons.

These are designed to be printed with no supports

The STEP file is included so that dimensions can be changed if needed.
