Arduino Pro Micro holder for Media control volume knob

A holder for the Arduino Pro Micro in the Media control volume knob, this way you don't have to hot glue it in place. (That's an Arduino Pro Micro, not Arduino Micro as is sometimes shown and linked to by Prusa's blog post and video.) Loosely fits in the existing opening of the volume knob. Not compatible with Arduino's with wires or pin headers facing downwards, have them face upwards instead (see 4th picture). Also comes with a reinforced bottom, modified to fit the Arduino in this holder, though the recommended closing method of twisting will not work due to the hole being filled by the holder.
