Here's my newest creation from the 3d printer. I want to do the tests and adjustments on the record changer, but I just sent my idler wheel in to Voice of Music to get a replacement. Since the motor drives the idler, and the idler drives the platter, and the platter drives the mechanism, there's no way to do the tests and adjustments without the idler. So I designed and printed one. It's 3 pieces: hub, wheel, and donut (printed with flexible filament). I had some bearings with the proper inside diameter, so I designed it around them. There is one spot in the cycle where it needs a little help, but otherwise it works well.
