The title says all. You can connect two hoses together by using hose clamps or other similar.

Print hint: Print in upright position, use brim at least with the smaller connector. 40% infill gives more strength for tightening the hose clamp. The overhangs on the top part of the connector needs support.

For me it took 1h 20min to print the smaller and 5h 25min the bigger one.

UPDATE: Added hose connector also for a 32mm inner diameter hose.

UPDATE 7.8.2025: Added versions with small chamfers in the middle part to avoid use of supports. STEP-files added to allow easier remix culture.
