Gardena barrel coupling

thingiverse

I required a straightforward and leak-proof method to attach a Gardena coupling to my water barrel so I could fill it efficiently. The Gardena 'bolt and nut' components are what I devised as a solution. You will need an rubber O-ring for the Gardena tip. The bolt 'flange' features two sealing rings at its outer diameter. It is also possible to utilize a rubber O-ring here, if preferred. Print with sufficient fill density (I used 30%) so that the print can withstand the rotational force when tightening. Please note that the barrel's wall cannot be too thick, or else the female Gardena coupling will collide with the nut. To modify the design, please download the SolidWorks file.
