Ball bearing sorter cups for bicycle sized bearings

prusaprinters

Quickly sort bicycle sized ball bearings into their individual sizes.Remix of original by pennyfarmer to make them printable without supports. I also did away with the 8mm bearing size as I don't come across those. Sorts ¼", 7/32", 3/16", 5/32", and 1/8" bearings. If you notice in the photo, I didn't have any 7/32" bearings so that cup stayed empty.To use, stack them with the smallest 1/8" at the top, in increasing size. Dump in a small handful of bearings and shake, and the bearings will stay in the cup with the marked size. Alternatively, you can run them one at a time, but stick with the large to small order, otherwise it won't work.Full credit to pennyfarmer for the original, I just remixed it to not need supports and print much faster. This works easier and more consistently than another design I still haven't perfected.

Make sure to use a slicer with Arachne, such as PrusaSlicer 2.5 or higher so the walls should be only two shells. Infill doesn't make much difference, use whatever you want.
