Measure both ends — inside or outside, your choice per port — set engagement lengths and a transition, and get a printable adapter. Shop-vac to tool port, dust collection to bandsaw, pond pump to garden hose: the geometry rebuilds live as real CAD.
Each parameter below rebuilds real geometry on every change — this is parametric CAD, not a scaled mesh.
| Parameter | Default | Range | What it does |
|---|---|---|---|
| End 1 diameter | 58 mm | 10 – 150 | Diameter of the first port. |
| End 1 fits | outer | inner / outer | Whether END1_D is measured inside or outside the hose. |
| End 1 length | 40 mm | 10 – 100 | Engagement length of the first port. |
| End 2 diameter | 32 mm | 10 – 150 | Diameter of the second port. |
| End 2 fits | inner | inner / outer | Inside or outside measurement for end 2. |
| End 2 length | 40 mm | 10 – 100 | Engagement length of the second port. |
| Transition length | 20 mm | 5 – 80 | Length of the tapered section between ports. |
| Wall thickness | 2.4 mm | 1.6 – 4 | 2.4 mm = six perimeters, airtight and stiff. |
For a port the hose slides OVER, measure the hose's inner diameter and set that end to "outer" fit. For a port that slides INTO a hose or machine, measure the receiving hole's diameter and use "inner" fit. Add nothing — print tolerance is built in.
PETG is the sweet spot: slightly flexible, so tapered ports seat airtight, and it tolerates the heat inside shop-vac hoses. PLA works for light duty; TPU only when you need a stretchy push-fit.
The generator covers straight tapered adapters. For a 45° bend, hose barbs or a stop flange, open the model in the workbench and ask the AI agent — it edits the same parametric CAD.
