Enter the pipe's outside diameter — 20 mm by default — and get either the plastic jaws of a DIN 3015-1 light-series clamp, sized from the standard's table with M6 bolt holes, or a one-piece two-hole saddle strap for screwing a pipe or conduit to a wall. The DIN jaws stand apart by the standard's tension clearance, so tightening the bolts grips the pipe.
The real generator runs in your browser: set the parameters, then download STEP or STL. Nothing to install, no sign-up.
The first open downloads the CAD engine (about 20 MB).
Each parameter below rebuilds real geometry on every change — this is parametric CAD, not a scaled mesh.
| Parameter | Default | Range | What it does |
|---|---|---|---|
| Pipe outside diameterPIPE_OD | 20 mm | 6 – 101.6 | Measure the pipe; for DIN 3015 it picks the clamp size. |
| Clamp typeTYPE | din3015 | din3015 / saddle | DIN 3015-1 plastic clamp jaws, or a two-hole saddle strap. |
| Bore clearanceCLEARANCE | 0.4 mm | 0 – 1 | Added to the pipe diameter; plastic pipe often measures a little over nominal. |
| Strap width (saddle)WIDTH | 25 mm | 12 – 40 | Along the pipe. |
| Tab length (saddle)TAB | 14 mm | 12 – 30 | Each screw tab beyond the arch. |
| Screw (saddle)SCREW | M4 | M3 / M4 / M5 | ISO 273 medium clearance holes. |
| Countersunk holes (saddle)COUNTERSINK | on | on / off | Seats for ISO 10642 countersunk heads. |
Every parameter can go in the page's link, so one link opens exactly the part you want. Example (Two-hole saddle for a 25 mm pipe):https://www.forgent3d.com/en/generators/pipe-clamp-generator?TYPE=saddle&PIPE_OD=25
The size the generator picks at the default 0.4 mm clearance, with the jaw-pair length, M6 bolt spacing and height from STAUFF's table (all 30 mm wide). Each row opens the generator on that pipe.

PPR water pipe: 20 (½"), 25 (¾"), 32 (1"); a bore that would leave under 0.5 mm of plastic beside a bolt hole moves up one size.
STEP AP214 in millimetres, exact B-rep — it opens directly in SolidWorks, Fusion, FreeCAD, Onshape or Inventor, and goes straight into a CNC quote form. STL for the slicer is one click too.

Press “AI edit” in the generator and say what to change — a keyway, holes, a different shape. The AI edits the part's model.py and it rebuilds in your browser, with undo. A few edits a day are free without signing in; to keep the result or go further, copy it into your models and continue with the AI agent.
Edit with AI →For bigger changes, several rounds, or a part you want to keep: copy it into your models (free account). The Forgent3D AI agent reads the model.py, edits it, rebuilds it and checks the result itself.
Copy and continue with the AI agent →A DIN 3015-1 clamp is the two jaws between a steel cover plate on top and a weld plate (or rail) underneath, held by two M6 bolts; size 3 uses M6 × 40. The plates and bolts are standard bought parts — the generator makes the plastic jaws.
HYDAC's recommended spacing for light-series clamps grows with the pipe: 1.0 m up to 12.7 mm, 1.2 m to 22 mm, 1.5 m to 32 mm, 2.0 m to 38 mm, 2.7 m to 57 mm, 3.0 m to 75 mm.
That is DIN 3015's tension clearance (0.4–0.8 mm by size on STAUFF's bodies): the jaws touch the pipe before they touch each other, so tightening the bolts clamps the pipe. Leave it — don't sand the faces flat.
Open https://www.forgent3d.com/en/generators/pipe-clamp-generator?PIPE_OD=20 — the two plastic jaws of a size 3 light-series clamp: 50 × 30 mm, M6 bolts 33 mm apart, a 20.4 mm bore. The steel cover and weld plates and the bolts are bought parts; export STEP to place it in CAD.
