Tardis Valve Cap (Schrader/Car)

thingiverse

My wife had been searching for valve caps for her new car, and I had promised weeks ago to try and find something that would interest her. Weeks later, I stumbled upon the Parametric Tardis model by Gossamer, and I barely needed to make any modifications. I took the "Small" tardis into Tinkercad and widened the hole slightly. This model is not threaded, so it should be a simple print. You simply need to print these out standing upright and screw them on - the threads will cut into the soft plastic and be, more or less, securely attached. Feel free to reduce the size by 5% for a tighter fit, but I found that at that point I was forcing it too much, and ended up with the current size.
