Air Tank Valve Guard

thingiverse

I built a protector for my air tank valve. The diameter of my tank is 28.52mm, where this guard attaches, and the total height of the whole guard is 115mm - blue plastic color on images. Also, I made a version for a 43mm tank with a 125mm height - black plastic color on images, it fits a U.S. 5 lb. CO2 tank. Thanks to Kenneth! Your tank may be different and this is why you might like to download the original design and modify it: 28.52mm version: https://a360.co/2OTLECj 43mm version: https://a360.co/369fXv2 I printed mine from PLA with a high (50%) infill ratio, and of course I can break it, but the main goal is to prevent accidental valve rotation. So far (3 weeks of usage) it stays solid and works well. It may not work with scuba tanks because usually they have a valve on left/right side. To assemble the 28.53mm version you will need: * 10 washers M4x9.0 mm * 2 screws M4x20 mm (20mm+, but not shorter) * 3 screws M4x35 mm (35mm+, but not shorter) * 5 self-locking nuts M4 To assemble the 43mm version you will need: * 12 washers M4x9.0 mm * 2 screws M4x20 mm (20mm+, but not shorter) * 4 screws M4x35 mm (35mm+, but not shorter) * 6 self-locking nuts M4 Enjoy! Let me know if you do anything cool with it.
