This is a protective case that I made for the TPMS system that I use on my camper. The case has space for all 4 TPMS valve stem caps, the display, the wrench and nuts that come with the sensors, as well as some extra space for some regular valve stem caps. I printed in PLA. Case prints in 2 halves that slide together. The brand of my TPMS is Jansite but I think this would work with others too.
