Printed rivet is on the left side in my photos. This rivet is similar to PN 90467-07055-C0 or Auveco #16784. They are used in the MR2 Spyder Frunk to secure the large plastic cover. They are a clever reusable push-pin rivet, where you push the center pin flush to latch the rivet. Push the center pin further to release the rivet. Then push the center pin back out to reset the rivet for re-use. I designed these rivets to have a very secure latch in the "open" position so the center pin won't go clear through and disappear. I printed mine with PETG and .12mm layer height. Printed on a PEI plate, the surface texture is very similar to the original rivets. It's worth experimenting to see what works best for you. Mine aren't as durable as the real rivets from Toyota, but they aren't as expensive either. I've been paying 65 cents each for the real ones.
