Gardena bend protection nut 1/2" / Gardena Knickschutzmutter 13mm
prusaprinters
Based on Sound-Maker's idea, I designed a Gardena anti bend nut to prevent the hose from bending. (https://www.printables.com/de/model/4324-gardena-spannmutter-fur-12-schnellkupplung/comments/755396)Gardena has these articles also on sale: Premium Hose Connector 13 mm (1/2") - 15 mm (5/8") (18255-00.610.00 & 18253-00.610.00)I have tested the nuts with some hoses and also hose connectors and it works fine. I noticed that some threads are smoother than others (different types of couplings & manufacturing year). After a few times off and on turn everything is smooth. So do not be deterred here ;)Attention: due to the print, the chamfer on the thread start is no longer present. Here you have to redraw the chamfer with a deburrer (see picture).I printed some parts in 3DJakes PETG (black & orange) and some in Extruder XPETG (red & white). All works fine. Printed in 2h on ELEGOO Neptune3 PRO with a 0.4 nozzle and a layer height of 0.2. But I think other settings, materials etc. works. Use what ever you want. ;) I recommend to use a simple support (see picture)Enjoy
