Extra Panels for R2D2 Modular control unit

These are three additional panels for printingbuddy's Modular control unit for R2-D2. 2 of them are for DROK buck converters and 1 is for a Teensy Audio shield for running sound from Human Cyborg Relations. All of them are made to embed M3 heat inserts. I used M3x5.7x4.6 brass inserts.
