Ever lose a valve stem cap?

'nuff said. ;-)


Print. Remove from print bed. Walk out to car. Screw on the cap. :-p

There are no internal threads. The first time you use it the stem will cut the threads into the cap.

...so be careful how you align the cap with the stem the first time! ;-)

I found my wife's car and mine had two different stem diameters. You may have to slightly adjust the internal diameter to make it best fit your car. There's a variable, "intdia", and a comment inside the OpenSCAD file for this.

Worked for me printed at 100% .15mm resolution

Worked great for me, printed at 98% !

need a tire stem valve tightener on the top :)

I changed the OpenSCAD code so you have more control over the internal size... and shape.

The internal diameter (int_dia) variable is now broken into a "high" and "low." High is deep inside the cap. Low is the mouth of the cap. Play with the settings until you get exactly what you need.

I was kind of surprised at the variance between the sizes of valve stems on different makes and models. You'd think this is "one size fits all," but apparently not.

If you don't use OpenSCAD, send me a note at [email protected], give me an idea of what dimensions you need and I'll e-mail back a .stl for you.

Thanks for the design. For Australia, I used high_int_dia=3.8 and low_int_dia=4.0, using TPU, 100% fill. A nice firm fit. But note that the *_int_dia values are actually radii, not diameters!

I guess that's better than my previous solution -- hanging around gas station air pumps looking for the caps that other people lost!

Sure beats a trip to the store!
