In our office at JAM Arch, we use a BIG stapler to staple drawing sets and we have a few different sized staples. Finding the size you want and determining the size left in there is one of life's small annoyances so I modeled a sorter that sorted 1/8" to 1" staples. Our printer wasn't big enough so I made this one that sorts the common sizes for us:
1/4" (Standard Office Size)
3/8" (Small drawing sets)
1/2" (Big drawing sets)
5/8" (another size)

Once I test print this and feel my model is good I will also upload the larger sorter for people with big printer or who would like to split it.

I will update this when I test print, but I listed what I plan to print with. Pretty simple print it would seem...
