3D printing1 partBeginner-friendlyNo supports
A double hose barb that joins a 13 mm (1/2 inch) and a 19 mm (3/4 inch) garden hose, both sizes measured on the inside of the hose. It is made for low pressure, for example at a rain barrel or on a drip line – not for a tap at full pressure with a closed spray nozzle, and not for drinking water. Push each hose fully over its barbs and tighten a hose clamp on both sides; printed in PETG, it lasts longer outdoors than PLA.

Worked for others:
Tip: Print standing as shown, no supports needed. With 3–4 walls (perimeters) it becomes watertight; a hose clamp holds hoses on the barbs.
Estimated by our slicer-like calculation for a 0.4 mm nozzle. Your slicer may show slightly different values.
