I was glad to find a cup from luks3D to replace the siphon of the security group of my water boiler, but I needed a full siphon.
So it's not really a remix anymore, I just took the screw, but that was the most complicated part to get correct... So I just built a full siphon around it.
It has a border to avoid water from spilling during checkups, and uses an output fitting of 32mm, adapted to fit a 30mm female PVC pipe.
I made it the most compact as possible, and it uses just 40g of PLA, with 4 perimeters (the body is 100% filled), which is over-killed... But at least it is strong.

To print it, put it straight on it's base, and just paint some support under the output tube top and bottom end. The rest should be fine with bridging. Use a 10mm brim to be safe.
