Dropped a box of abt 900 washers on the floor. Manually re-sorting was not fun at all, so I printed these simple sorters.

There are six sizes of washers in the box, so I needed 5 sieves. The file name describes the hole size in the step file, so they might print out a little smaller, depending on your printer and slicer settings. I printed them on a Ratrig vcore3 from ABS with no hole size compensation and they did the job.
