CNC Clamps

thingiverse

Clamps to fix material during CNC machine work. Instructions Uploaded STL's are designed for material of 19mm thickness. Testprinted in ABS. Two clamps on the same side of the material gave enough grip so I hardly couldn't move the material so I'm sure having clamps on 3-4 sides of the material will be more than enough to hold it tight. M4 machine screws are used to mount it to my CNC table (MDF with drilled holes). One model with ha single hole (fixed distance for mounting material parallell to the drilled holes which was drilled by the machine and should be perfect parallell to the gantry). The other uploaded STL model has a slot for the screw to be able to freely mount it. The two meassurements circled in blue on the drawing are the important ones. 19mm which is the material height and 3mm which was the flex for a tight grip. Should probably work fine for material 17-19mm thick. The ABS is flexible and was pulling down the material enough so it didn't neither break the plastic or destroyed the drill holes.
