R8 Collet Carousel

You may have seen R8 carousels for sale at Enco or Little Machine Shop. Here's a quick and dirty 3D printable carousel. It uses 2 skateboard bearings and a 3" 5/16 bolt with a nyloc nut. Use a washer at the top, in the middle and at the bottom. It will hold 12 R8 collets. It needs just a little bit of support for the lower bearing on the lazy stl. The stl files are in SAE units so you'll need to scale them when printing.
