3D Printing Corner Jigs and Pipe Clamps for CNC

The collection gathers STL files for clamps, corner jigs and add-ons that appear in Mostly Printed CNC builds and in general workshop setups. It covers pipe clamps drawn around a tube diameter, right-angle brackets, parametric clamps and workholding for a machine bed. This is useful when you are assembling a frame or need to hold a part steady during 3D printing or machining.

«3D Printing Corner Jigs and Pipe Clamps for CNC»

The models fall into a few groups. Corner clamps and angle jigs hold two parts at a right angle while glue or fasteners set. Pipe and conduit clamps grip a tube of a given outer diameter, often to fix it to a frame. Add-ons for a Mostly Printed CNC extend the frame with end caps, feet or corner blocks, and a separate group covers low-profile workholding for a machine bed.

Before printing, read the author's page for the tube diameter or pipe size the clamp is drawn around, since a few millimetres of difference changes the fit. Check how many parts the model has, whether screws, bolts or threaded inserts are needed, and whether the geometry calls for supports. The material and settings the author lists, along with photos of real prints, tell you more than the title does.

If a search returns too little, try related terms: angle bracket, corner jig, conduit clamp, hose clamp, workholding, or the name of the machine the part belongs to. Searching by the pipe diameter, such as a nominal size in millimetres or inches, narrows the results further. Parametric versions are worth a look when you need a different size, because you can change the dimensions in CAD before exporting an STL.

FAQ

常见问题

What counts as an add-on for a Mostly Printed CNC?
It is a part that attaches to the frame or the moving assembly rather than replacing a core component: end caps, feet, corner blocks, cable guides or clamps that hold a pipe in place. The reference titles show both small fittings and larger structural blocks.
How do I match a clamp to a pipe?
Find the outer diameter the model is drawn for and compare it with your pipe or conduit. Wall thickness and material affect the outer diameter, so measure the tube you have rather than relying on a nominal trade size.
Do 90-degree corner clamps need extra hardware?
Some are held by a single screw or a bolt and nut, while others rely on the printed geometry alone. The author's page usually states which fasteners are needed and where they go.
How can I find a version in another size?
Search for parametric models of the same part, or add words like parametric, adjustable or custom to the query. In a parametric file you edit the dimensions in CAD software and export an STL at the size you need.
