3D printing

Has anyone else started doing this? I am having the time of my life, being stuck at home, and playing with my recently acquired 3D printer. I have just finished designing and printing a bunch of parts for my car, and anyone else who would be interested, by the way. I have designed a 64 Dart GT emblem for the hood trim and the trunk piece. I have designed and printed a center ring for the 64 tail light, that I will either be painting with chrome paint or sending out to get vacuum metalized. I have designed and printed an offset reducer coupling for modern defrost hose to go on 64 heater box. And I have designed and printed dozens of useful gadgets and hangers for the workshop and home. And as a result of making the trunk piece, I tweaked the design and I am making guitar picks for my kids and grandkids! I think that if anyone that has any sense of squareness and proportion, tried working with one, they would love it. Just sayin
