CMM fixture and fittings for X-UHF project

This is a cheap and non-millimetre wave compliant RF prototyping station. It's a simple ~1/4" (6.5mm) pitch CMM breadboard that can be used to bolt down modular circuits and connect them with GSG bridges.

After printing each hole is manually, and painfully, threaded with an M3 tap and then de-burred with a 6mm drill bit.

I'm currently working on PCB modules in this repository https://github.com/calston/x-uhf
