The water tap adapter broke in my irrigation controller. I tried 3D-printing a replacement part. Here's my final attempt before ordering an original (injection moulded) spare part. The dimensions are right, it fits the body of the valve, but FDM printing is just not perfect for this kind of parts that work under water pressure. I've tried several attempts, but I still got some minor leaking. Try it at your own risk - maybe you will find better filament or better settings and it will work for you. Source file for Fusion 360 included in case you might want to tweak the design.
Remember to use the original o-ring seal.
My best performing print settings (with my Prusa MINI+):
- layer height: 0.15mm (with 0.4mm nozzle)
- filament: PET-G
- supports: yes, on overhangs
- perimeters: 8
- seam position: random
- infill: 100%
- speed: reduced to about 75%
- temperature: 245C
- extrusion multiplier: 1.1
