Issue: PSU high voltage contacts are exposed, no AC on/off power switch Solution: put a cover on PSU, add on/off switch, add placeholders for additional 5V DC-DC converter for future Raspberry Pi upgrade (two options for vertical and horizontal mount). Overall budget: ~$3 BoQ: AC Power socket with switch and fuse: http://got.by/3jt6h4 DC-DC 5V 5A module, high quality (synchronous, TPS40057): http://got.by/3jt510 DC-DC 5V 3A module, conventional (LM2596): http://got.by/3jt5qh 4 x M3 3X4mm thread brass inserts: http://got.by/3jt4pc Two models: one designed for brass thread inserts for extra DC-DC converter (inserts to be injected by a solder iron at about 150*C) one with thread modeled (might require extra threading) Inspired by https://www.thingiverse.com/thing:3225570
