No supports required. Just slice and print!!

4 Versions available:

Shark_vX_A.stl: Original design, movable jaw
Shark_vX_B.stl: Friendly face, movable jaw
Shark_vX_C.stl: Original design, NON-movable jaw
Shark_vX_D.stl: Friendly face, NON-movable jaw

The non-movable versions are intended for children, as teeth are quite sharp. Or just in case you have trouble printing the movable one.

I STRONGLY RECOMMEND printing the test head first to check everything works fine. there are small variations between filaments, so you may need to adjust the XY Contour compensation (increase if teeth are loose or broken, decrease if fused).

After printing, the tail and the jaw should get free with a little force: https://youtu.be/14z1ll9yMmU

Then just enjoy it, even in the water!! https://youtu.be/E1W-RyH8bGA https://youtu.be/aV-XhMr7Edc
