Bicycle CO2 inflator protective stoppers for cartridge and inflator (flexible)

thingiverse

A set of flexible protective corks for the CO2 inflator and unopened cartridges (3/8" or 9.5mm thread) that allow you to throw them into a bicycle bag loosely without them getting dirty or the gas escaping. As for the smooth cartridge protector, it can be a bit hard to screw on, so I made a ribbed version. I was a little worried about making those rigid and threaded, as those could snap off and end up stuck inside- the last thing you want when marooned far from home on a bicycle with a deflated tire and exhausted after a day of cycling, so I made them flexible, so they can be both pressed or screwed on despite the lack of thread. Print both flat side down for best adhesion.
