Step Clamps M6 for CNC

Over the time more and more of my CNC clamps broke or became a vicitim of the drill-bit. So it was time to make some new and I wanted to add some lernings from the last years. This is nothing game changing, just some simple clampls with steps on both sides. There a 6 clamps and a counterpart. 3 different lengths and for each length a version with the steps both on bottom and a version with the steps swapped (one bottom, one top)
