really cool design, however 2 out of 4 had a fin needing glued in place as breaking it loose broke it off and one of the jaws had a socket break and half the teeth tips came off when I broke it loose also, if it was scaled up a bit more and if the fin wasn't sideways it would be perfect, would rate 5 stars but with 50% success I gotta say it's not perfect, but it may come out better to someone else with different filament or something
