Here's my latest designs - replacement pins for the sun visors. The one on the left is the original part from my one remaining good visor. The middle one is a version where I successfully modeled the rotating end of the original. And the one on the right was my first try, which is just a solid, one piece pin. I printed the solid one, and the base of the rotating one in PETG. The cap of the rotating version I printed in TPU, in order to snap it over the clip that holds it on the base. I snapped it onto the base when it was still warm straight off the printer, it went on real easy but I can't get it back off, tolerances are kind of tight. I couldn't get a PETG cap to go onto the base at all, it wasn't flexible enough.
