Volume knob box for micro USB DIgispark

A volume knob box for the micro USB Digispark (20mm x 18mm). It is made for a rotary encoder with a shaft diameter of 6mm and a shaft length of 15mm. A hole for a 5mm LED is given to illuminate the knob. Proven clam-shell design. You'll need 4 M4 Screws (10mm or 16mm). No nuts required.

I suggest a dark color for the base and white or transparent for the knob.

Digispark offers 4 I/O pins. 2 are required for the encoder (P0, P2), one for the encoder pushbutton (P5) and one for a signal LED (P1).
