Digispark USB Volume Knob (micro USB jack)

USB volume knob using Digispark with micro USB port.

The Digispark used has a micro USB port so I modified the top and bottom of the case in SketchUp to accommodate the port. I created separate standoffs for mounting the board instead of taking the time to incorporating them into the bottom.
I also redesigned the colored ring by adding a lip around the outside of the top to hide the gap between it and the case.
The screws I had on hand were a little long for mounting the board so I created a pair of spacers as well. With 1/4" screws spacers wouldn't be needed.
