An exploded T-Rex skull split into 6 sections with 5 points of articulation. The finished display exposes inside skull cavities for classroom study and discussion.

A fun model for students to assemble, pose and discuss.

Files include adjustable T-Rex hinges designed for 3D printing, the sectioned T-Rex skull, and a modified base.

Print one copy of each skull piece, with support. (Optional) Flip the three top center pieces on their sides to print with less support .

Print the hardware without support. They look good in sliver or black. You could do it all in one build, or do the bolts separately since they could benefit from a skirt if they don't stick.
For the hardware pieces you need to print are:

5 T-Rex Bolts
1 T-Rex Hinge Center
5 T-Rex Hinge Threaded
3 T-Rex Hinge Unthreaded

Then you need to print the base and modified rod. I like black.
