More info on the build can be found here A quick little sorter/organizer for BHCS and SHCS metric bolts. Just stack them up, from smallest to largest, pour in your assorted bin of M2, M3, M4, and M5 fasteners, pop on the lid, then give it a good side-to-side shake. And that's that!

All five parts* print on a single build plate on a Prusa Mk3s, and print in a little under 7 hours (full slicing info in the 3mf attached). The * is because I also made a funnel top piece, but I don't really think it's worthwhile. I included it just in case someone wants it as much as I thought I might :)
