Another filament turntable

Two plastic thingies with a 608zz (8x22x7) bearing in the middle. (If you have a Gregs Wade extruder, you already have four of these bearings.) I've included a 30mm and a 50mm spindle stl as those are the two spool sizes I have right now. I've also included my autocad dwg file. Ideally, you want the bearing fitting snugly into the lower and upper turntable parts. Some tweaking on your part may be necessary depending on your particular printer. Tested with a brand new 2kg spool and it spins
