Workpiece Clamps

thingiverse

Print the handle once. Print at least two or more pairs of the pivot + wedge. Print at least three or more edge support pins. Stick the pivot into the wedge. Plug the pivot then into a workbench hole (my workbench has 20mm holes in diameter, at a matrix of 96x96mm) and use the handle to tighten or loose the clamp to fixate your workpiece in place.
