This is a cool accessory that goes on the tube valve of your bike but make sure its a Schrader valve otherwise it won't fit, I oftentimes unscrew and roll it to see what trail I am going to ride. I printed about 10 of them in white PLA and just painted them to my liking.
Print settings:
Print it with the threaded hole down
Infill density: 15%
