CGA 320 Valve Wrench for Co2 Tanks

thingiverse

Here's a handy wrench for swapping out your CO2 tanks from whatever devices. It fits perfectly onto the stem of a CYA 320 valve, making it easy to access without having to search for a wrench every time you swap. I printed it at 75% infill and 5 outer shells. If that's not strong enough, there must be something wrong with your printer or you're over-tightening your valves.
