This is a remake for 3D printer based on an early 3d model I made using 3D printing pen.v1.v2. (shortened the body, and made it more round)v3 (this model, mainly based on the v1, with bigger eyes, and 7 fins like a real shark, adjusted the fin shape.) v4 (the first model with 3d mouth and 3d teeth.)v5 (bigger3d mouth and longer 3d teeth.)v6 (change the shape of the teeth and have fewer teeth, look happier ) Please comment on which one is your favorite.
