Hold-Down Clamps for CNC, Laser and Woodworking: STL Models

«Hold-Down Clamps for CNC, Laser and Woodworking: STL Models»

Clamps for CNC tables usually follow a T-slot or a stepped profile that slides into an extruded track, and most designs use a screw or bolt to pull the arm down onto the work. Laser honeycomb variants tend to be flat and low so the cutting head can pass over them, and they often grip the bed with pins instead of tracks. Woodworking versions are built around bench dog holes or rails and are generally chunkier, since they hold larger panels and boards. Kits and bundles group several arms, risers and contact heads so one set covers different heights and materials.

On the model page, look at the stated size and scale first: the arm length, the thread the clamp expects, and the height of the profile decide whether it fits your track or hole grid. Check how many parts there are and how they assemble, whether the author lists supports, and which material and settings were used. Photos of real prints show how the threads, the sliding surfaces and the contact face come out, which tells you more than a render.

If a search returns too much, narrow it by machine or fixture type: track clamps, bed pins, bench stops, edge clamps, toe clamps or fixture plates. Related terms such as workholding, fixturing, back stop, riser or low-profile clamp often lead to the same family of parts. Searching by the bolt size or the track profile, rather than the word clamp on its own, usually gives a shorter and more relevant list.
