Tyre Valve Dust Cap Replacement - Schrader and Presta + Upgrade Designs - Car or Bicycle

Made for the Replacement Parts contest.  

The core model is a functional replacement for Presta and Shrader type dust caps as round on most cars and bicycles. 

After printing check internally for any hanging plastic which could depress the tyre valve and deal to deflation. The top of the valve is domed to help avoid this.

I couldn't resist having some fun with the design and have included some different options. More designs to come!

Quick to print and using minimal filament, these replacement dust caps for Presta or Schrader valves will get you out of a fix or offer a fun upgrade to the traditional designs.

I've printed these at a .2 layer height, they are a nice smooth fit and the threads mesh well with the valve threads. If you find your printer produces them with a too loose or tight fit, please let me know - trying to fix with a very small % enlargement or reduction should ensure a good fit.

Edit 21/09/2023 Reshape of Presta Replacement valve dust cap (v2) to conform more closely with original design.
