Tire Valve Cap and TPMS O-Ring

###If you've already downloaded it, please resize the cap to 10mmX10mmX14.29mm. If you haven't downloaded it yet, I have uploaded the correct size. My bad. Remixed muzz64's Tire Valve Cap. I removed the MakerBot logo and added a dome top, reducing the size slightly from 10.5mmX10.5mmX15mm to 10mmX10mmX14.3mm. The cap can fit a standard o-ring if you're missing it or try printing the one I designed. ###**Printing the Tire Valve Cap** I recommend printing the Tire Valve Cap at .1mm layer height, either 2 shells at 100% infill or 4 shells which should make it solid. So far, I've had no issues with PLA, but you may want to go with a sturdier material like ABS or PETG. I recently completed a vacation driving 250+ miles both ways without issue. I was using the actual o-ring from the previous cap that had cracked. ###**Printing the O-Ring** I haven't tested the O-Ring thoroughly, but if you decide to print it, I recommend printing the O-Ring in TPU/TPE at .1mm layer height with 2 shells at 100% infill. It's a bit thicker than a normal one which should help with stems being pressed in and releasing air. When inserting the printed O-Ring into the cap, place it so that the first layer/bottom is facing outward as you put it in the cap. You can then either push it in using a pen or other small tool, or screw the cap on which should force the O-Ring into the cap.
