CNC edge hold-downs

thingiverse

I recently built some edge hold-downs to complement my low-cost Chinese CNC machine, perfect for working with small sheets of material and situations where I need it lifted just a few millimeters off the bed. To go along with them, I decided to create corner hold-downs as well, which you can find here. The designs have a dual chamfer feature, making them versatile enough to be used whether the sheet material is lifted or not. Additionally, I've included an OpenSCAD file for customization purposes. The file includes a $holderwidth variable that allows you to adjust the hold-down width from its default setting of 20mm. As a result, you should be able to use OpenSCAD or the Thingiverse Customiser to create versions with whatever widths suit your needs for various types of milling, lasering, or cutting operations.
