Gridfinity bin designed to hold 18 small size binder clips.

Couple notes:

The shape triangular part of the binder clip isn't very consistent so the pegs that hold them in place are a bit undersized.

I've also included the F3D file if you want to make changes. I don't have much experience with Fusion 360 and this was one of my first attempts so don't expect the most user-friendly file though.
