PipeFit generates 3D-printable pipe and tube fittings from a handful of numbers. Pick a fitting, tweak the diameters and lengths, watch the 3D preview update live, then download an STL ready to slice. Everything runs on your device — no upload, no account, no per-use cost.
Straight Coupler
A plain tube: outer diameter, bore, length.
Reducer
A tapered tube joining two different outer diameters.
End Cap
A closed tube that plugs one end of a pipe.
Elbow
A curved hollow tube bend, angle adjustable.
Tee
A T-junction with an independent branch diameter.
How it works
Each generator builds its mesh with Three.js directly in the page — lathe-revolved profiles for straight and tapered tubes, an extruded annulus swept along a curve for the elbow, and merged tube segments for the tee. Nothing is sent anywhere: the STL is assembled and downloaded straight from your browser's memory.
