Summary I had some left over 696 bearings from printing a copy of thing:2194520 and figured why not make them into a small spinner! So I made my first design in Fusion 360 and this is the end result and I'm very pleased! Cap's and bearing's fit perfect, might need to tap the bearings in to fully seat, but they should be flush on both top and bottom. The caps fit great by hand and don't rub. There's 2 sizes, the smaller is 12mm to let you see the bearings underneath just a bit, and the larger one is 15mm (the same size as the bearing itself) so it gives a nice clean look, and as small as these are, a little more room to grab. And of course I had to make a few versions with different numbers and designs, and we all wanted to see how many would fit, so of course I had to release the 7 lobed version as well :D Hope you enjoy! amazon link to 696 bearing's I used: http://a.co/boVcWu2 edit - last few pic's were just to show size comparison between these and standard 608 bearing spinners edit 05/08/17 - Added thicker versions of the cap's for those having loose fit's. Print Settings Printer: Anet A2 Rafts: No Supports: No Resolution: 0.1 or 0.2 Infill: 50-70% Notes: I've printed in both 0.2 and 0.1 just for testing and both came out just fine, the fillet is a bit more noticeable on 0.1 obviously but both have soft, not sharp, edges off the platter so that's really all I wanted. I printed this in black PETG by eSUN. 2 walls, 0.4 nozzle, 50mm/s print speed, 25mm/s outside perimeters, 70% "lines" infill sliced in cura 2.04 (still having first/second layer issues in 2.05) and they come out great! Fast too! at 0.2 they take less than half an hour, and less than an hour at 0.1. Sweet!
