Gardena Profi to 1/2'' inch hose
thingiverse
A somewhat cheaper option for connecting a 1/2'' hose to Gardena Profi is using a 3/4'' Gardena connector instead of a standard 1/2'' hose Gardena Profi connector. OPMP Nové Zámky Aqua system compatible. Be sure this is Gardena Profi, which is larger than the common "small" Gardena system designed for use with 1/2'' and 3/4 hoses, so it won't work with them! A small handle has a hole to allow fastening the device to a hose when not in use to prevent losing it in the garden. Printed with Gardena facing down, using supports. The sealing O-ring can be purchased as a spare part or possibly printed from Flex material. I don't have experience with Flex printing yet. So far, I've tested printing on Prusa i3 and Pro3D ABS, and this fitting attaches to the OPMP Nové Zámky Aqua (Gardena Profi compatible) shown in photos easily. I haven't tried it without a sealing O-ring, but I believe it will work.
