Hold-Down Clamps for CNC and Laser Tables: STL Files

«Hold-Down Clamps for CNC and Laser Tables: STL Files»

The designs differ mainly in how they attach to the machine. T-slot clamps use a bolt that slides into the table profile, honeycomb clamps are kept flat so the laser head can pass over them, and G- or C-clamps rely on a screw thread and a wide jaw. Kits and stepped risers combine several parts to reach different heights, while parametric versions let you enter your own dimensions before exporting an STL.

Before printing, compare the model against your setup: slot width, table or bed thickness, bolt head size and the reach of the jaw. Look at the number of parts, whether the thread is printed or takes a metal screw, and whether the author expects supports. The model page usually lists the material and settings used, and photos of real prints show how the clamp sits on a table.

If the first search is too narrow, try related terms such as workholding, fixture, cam clamp, toggle clamp or spoilboard clamp. Adding the machine type, the table profile or the bed style narrows results further, and searching for the hardware you already have, such as a specific bolt or screw size, often brings up matching designs.
