CNC edge hold-downs

cults3d

I recently made some corner hold-downs for my cheap Chinese CNC machine, for working with small sheets of material and where I might want it lifted off the bed a few millimetres. To go with them I decided to make some edge hold-downs too, which I've uploaded here. The designs have a double chamfer, so they can be used with the sheet material lifted or not. Also, I've included the OpenSCAD file for customisation. The file includes a $holderwidth variable that can be changed to alter the hold-down width from the default 20mm I used. That means you should be able to use OpenSCAD, or the Thingiverse Customiser, to make versions with whatever widths you need for different types of milling, lasering or cutting.
