Not sure if anyone has tried this, I couldn't pull up a similar search result. Forgive me if this has been covered elsewhere. My kids like building plastic models in the summer between biking swimming video games and...summer school. I told them the parts trees could go in the recycling, then I thought wait,,,don't. They aren't cylindrical though - so just chuck a piece in the drill and run through a slightly smaller hole drilled in a piece of metal. Installed in a scrap, glued in with CA, sanded flat and sprayed with lacquer to see how the plastic reacts. Looks like the lacquer will not eat this type of plastic. Not bad.
