Gridfinity Quick Bolt Sorter (Parametric)

This is an automatic metric bolt sorter that fits into the gridfinity system. Stack them starting from smallest up to largest, place your bolts in the top bin and shake! Here's a video demo, which also uses this model by Lndnny to sort by length:

The holes in the bins are sized to only contain the correct bolt size. This works for standard socket and button screws, and countersunk up to M5. The STLs are all 1x1x4(32mm) bins that go from M3 to M6. The included .f3d file allows you to use larger bin sizes, and go as small as M2 bolts or as large as M16! (if you set NutHoleRowsColumns to 1)

This is a remix of BubsBuilds 's design , who I got the idea and dimensions from. I modified schenkzoola 's remix of pcnc 's parametric gridfinity file by adding fully parametric holes, and found a best fit curve using desmos to automatically calculate hole sizes based on the screw size.
