Pipe, hose and duct adapter generator
Give the two diameters and the lengths. The generator builds a reducer, coupler or funnel with a smooth transition in your browser and exports it ready to print.
Builds in your browser. The CAD engine downloads once (about 60 MB), then every part is local.
What to put in the prompt
- Say inner or outer for each diameter. A hose slides over an outer diameter; a pipe slides into an inner diameter.
- Give each end a length. 25 to 40mm is enough for a hose clamp.
- Give the wall thickness. 2mm for hoses and ducts; 3mm for anything under pressure.
- Ask for a barb, a lip or a stop ring if the hose needs to grip.

Duct pipe reducer
2mm thick duct pipe reducer, 65mm opening from one side, 50mm long reduced to 125mm other side. from both sides a neck 30mm
Frequently asked questions
Can it make a vacuum or dust-collection adapter?
Yes. Measure both ends with callipers, say inner or outer for each, and give a length. Add 0.5mm for a slip fit or subtract 0.3mm for a press fit.
Will it be watertight?
The model is a closed solid with no gaps. Whether the print is watertight depends on your slicer settings: use 3 or more walls and 100 percent infill on thin parts.
