Fluval Skimmer

Two Y-Tube modifications:

• First is an even cut if your water level is even with the return hose.
• Second is for if your hose is submerged, extended the skimmer side by 24 mm.

I’m using the taller skimmer version which extends 24 mm above the connection. It works better with my topped off water level. My water level was still a bit too high so I used the suction cup to keep it elevated until enough evaporation takes place. 

Even cut doesnt need supports with the top side down on the print bed. Extended skimmer tube version will need supports, I used snug and it came out with no issues.

Resized the Y Arm to have two different options on skimmer attachment height.
