Binding Clip

thingiverse

This is a scalable clip to bind together papers, it should work with between 3 and 26 sheets. It is currently 70 mm long. You can scale it in its long direction to cover the entire long side of a US Letter sheet (Scale to 11.5 in, about 4x in the long direction), to cover the short ways of a US Letter sheet (for landscape folios or booklet prints, about 3). To use on thicker stacks of paper, scale it up uniformly first. Maybe (your sheets)/15 sheets is a good factor? I don't know, no promises.
