5L bottle cap (50mm) (mod.)
thingiverse
I slightly modified this one: https://www.thingiverse.com/thing:4546778 - VERY good model! But the hole is too big for standard 9mm hose, plus i added some extra "spill protection". No support needed, best filament for this one is PETG. (this cap is a part of this project: https://www.thingiverse.com/thing:5884434 )
