Batman Bike Valve Caps

Fits snug on a schrader valve. I printed about a dozen of them in case I ever lose one. I still haven't lost one after removing and returning them several times and through vigorous rides on my RadRover.

If I were ever to make a new version of this, I would make it large enough to fit an actual generic valve cap inside the head and glue them together.
