CNC3018 PCB Clamps

This clamp was designed to ease the milling of pcb. It eases the height mapping as well. I designed it for 4 most usable thickness of FR4 leaf. It can also be used for holding a plywood or aluminium for engraving and laser cutting as well.

Parts needed
A. 2 or 4 clamps, depending on size of pcb
B. 4 or 8 M6 25mm bolts(screws), depending on amount of clamps
C. 4 or 8 M6 [cage nuts](https://www.thingiverse.com/thing:3038419), depending on amount of clamps
