Air Release Valve Cap

thingiverse

Made this cap to release air pressure from a tire without having to sit there waiting for it. Didn't want to spend money on a set of metal ones. This works just fine so far and is a quick print. Made two versions, one is a full size cap, the other is about half. They both work perfectly fine, so really it's just a matter of preference or if you want to save a little extra filament.
