I drew up a little binder clip also called paper clamp that makes use of a rubber band to clip in documents, notes, drawings and so on in your workshop, office or at home.
The two parts of the clip are held together by one or several rubber bands - depending on what type you've got - and keep their position with little round indents that match on the front and rear part of the two clamp parts, no pins or machine screws required, super simple - very functional!
