Introducing Mosasaurus!! This articulated model is packed with action features and has a subtle robotic flair. His flippers move and lock in an upright position. Mechanics inside his body link his tail together with his head. They move in opposing directions to create a swimming motion. Upper and lower jaws are linked by small gears behind his head. His mouth opens and shuts with a satisfactory snap sound! 😁

This model prints in place with the exception of his head (upper jaw). This prints separately and easily snaps in to place. No supports are needed.

Fits on a Ender 3 or similar sized printer. Can be scaled down to 75% if desired.
