Melzi Board USB Clamp

The USB socket on the Melzi Controller Board can get quite a bit of stress. After having to resolder it, I designed this clamp to take some of the strain.

The design uses an M3 8mm Cap screw, an M3 20mm cap screw, one M3 washer and two M3 nuts. If you've only got screws a bit longer, it doesn't matter.

It simply screws on to the mounting hole on the corner of the board.

Please note: This clamp blocks the micro SD card in its slot - it's a feature,not a bug. I hardly ever use the card. If you swap it regularly though, this design is probably not for you!
