Hold-Down Clamps for CNC: 3D Models and STL Files

This collection gathers 3D models of hold-down clamps used to fix workpieces on CNC tables, T-slot beds and T-track rails. It covers toggle and quick-acting designs, low-profile bodies and versions with swappable contact heads. The files are meant for 3D printing, so the choice usually comes down to your table geometry and the material you print in. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Hold-Down Clamps for CNC: 3D Models and STL Files»

The models split into a few families. Toggle and quick-acting clamps use a lever to press the workpiece down, while static clamps rely on a bolt and a shaped body. T-track and T-slot versions are shaped to slide into a rail and be locked at any point along it. A separate group uses interchangeable contact heads, so the same body can hold flat stock, round bar or an edge.

Before printing, read the author's page for the dimensions that matter: the rail or slot width the clamp fits, the clamping height range, the thread size of the bolt, and how many parts need assembly. Check whether the model is meant to be printed as one piece or in several, and whether the author lists supports, orientation, material and settings. Photos of real prints show how the clamp behaves under load better than a render does.

If the results are too narrow, try related wording: workholding, fixture clamp, edge clamp, back stop, cam clamp or toggle clamp. Adding the rail type or the stock thickness to the query usually narrows things down, while dropping the machine name broadens the search to general workshop clamps.

Clamps that press on a finished surface are often printed with a soft or separate contact pad, and that detail is worth checking in the part list. Scaling a model to fit your table changes bolt holes and thread clearances, so it is safer to pick a file already sized for your rail.

FAQ

Questions fréquentes

Do these clamps need supports when printed?
It depends on the model. Many low-profile bodies print flat without supports, while lever and overhang-heavy designs may need them. The author's page usually states the orientation and whether supports are required.
Which material works for a hold-down clamp?
Clamps take load, so stiffer filaments are common, and some designs are printed with a softer pad where they touch the workpiece. Check what the author lists and what your printer handles.
How do I match a clamp to my table?
Compare the rail or slot width, the bolt or thread size and the clamping height range with your own setup. Files are often named by these dimensions, so the title alone can tell you whether it fits.
How can I find more similar models?
Search for workholding, fixture clamp, T-slot clamp or cam clamp instead of hold-down clamp alone. Adding your rail type or the stock thickness narrows the results further.
