Car Plastic Underbelly Rivet

This is a rivet designed to hold the plastic underbelly of a car up to the chassis, much like the black store-bought version (shown in the cover photo). It was designed with the 2003-2008 Toyota Corolla in mind, but can likely be used on the vast majority of vehicles. I highly recommend that PLA is NOT used to print this, as the heat radiated from roads in most areas can be enough to at least deform it. A good recommendation for filaments:
PETG (any)

Anything else with a heat resistance above 69 degrees Celsius
