Bell syphon for aquaponics

Bell syphon I made for an aquaponics system. 

This is the outer bell, with a hole in the top to insert some aquarium air line tubing to help break the syphon.

I have added 3 STL's. One is the entire thing (not sure how well this will work because it was 2 bit for my printer) and the other 2 are the separate pieces which I printed on my Prusa MK3s.

If you print the pieces separately then make sure you use some form of sealant between the 2 parts. I personally used solvent cement.
