Pipe adapter to fit hoses with 10 mm and about 20 mm together.
Printed using PETG (outdoor use), 0,10 mm, 15 % infill
The author remixed this model.
Grooves were added to the bigger part of the adapter in order to hold a water hose at about 3 bar. It was used to connect the cyclone mist sprayer (https://www.printables.com/de/model/77407-cyclone-mist-sprayer) via a smaller diameter hose to a water hose.
Unfortunately I'm currently not capable of doing any reasonable design in SCAD, so I tinkered it together using FreeCAD, it's NOT parametric and fits only a specific diameter (bigger part: inner diameter 17 mm, outer diameter 22 mm, smaller part (conical): outer diameter from 7 mm to 9 mm.
