Genmitsu CNC 4040-PRO Clamp

Set of 3D print to replace the clamp for CNC 4040 from Genmitsu using their screw and nuts.

The design is inspired by the clamps used if milling machine : a stair case and a finger are    attached to the bed in a way that the pressure on the stock is exerted downward while blocking horizontal moves.

The filament I used was ABS, with no reason other that I wanted strength and I have 2 rolls of ABS left over from 10 years ago. I guess PLA will be ok.

The finger come in 2 length, I guess a mix (2+2) of both size is a good start.

The wingnuts are warmed before being inserted in the printed nut. One can replace the wingnut with a normal nut.

The model was created on OnShape. One can access and modify it by searching “Genmitu cnc 4040”
