Hollow Transition Tube

Create one single hollow tube, 150 mm total length. Outer diameter: 24 mm. Internal geometry from inlet to outlet: 25 mm straight circular section, 20 mm internal diameter. 30 mm smooth gradual change from 20 mm circular to 15 × 15 mm rectangular, with R2.5 mm rounded corners. 40 mm straight 15 × 15 mm rectangular section with R2.5 mm rounded corners. 30 mm smooth gradual change from 15 × 15 mm rectangular with R2.5 mm corners back to 20 mm circular. 25 mm straight circular section, 20 mm internal diameter. The inlet and outlet must have the same 20 mm internal diameter. The 15 × 15 mm section must be centered on the longitudinal axis. The total internal length must be exactly 150 mm. The internal passage must be continuous and hollow from inlet to outlet. The outer wall must remain 2 mm thick in the circular sections. Create one single watertight solid.

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
