Shark fin
thingiverse
Because who wouldn't want a shark fin, especially if it means not having to kill a shark to get one. A round bottom has a slot that fits a 2.5" wide belt and a curve so it should sit flat on an AL80 tank. A flat bottom has no slot and a flat base. Scale them down to 78% to fit a Prusa Mk3 when printing the fin vertically, but be aware that the web slot gets too small if you go smaller.
