Snapping Lizard Jaws
JAWS DO IT!
This is another single-print, integrated model of jaws moving in a printed ball-joint.
Nice demo of printed assembly of parts as well as another application of ball socket joints.
(Successfully printed on extrusion printer using a very thin raft and line-style supports touching the build plate (helps the ball socket get printed more cleanly))
Just be careful when you take the model off the printer.. It bites!
