Styracosaurus Puzzle Model

This is part of a project I was required to complete in order to graduate senior year of high school.

To accompany a toy tractor and lowboy set, I created a skeleton of a Styracosaurus. My mentor helped me laser cut the individual pieces that I drew up on Autodesk Inventor.
Number of pieces to complete the build: (29)
1x Mane
1x Backbone
2x Face plates
8x Ribs (A-H)
1x Front Hip & Back Hip
2x Front Legs
2x Hind Legs
2x Hip Bones
9x Tail Bones

Note: When laser cutting these pieces, I had to remove and replace all the splines in the ribs and backbone with arcs in order for the program to show all the lines of each piece.
I've uploaded all of the Inventor files and STL files for anyone's use.

If there are any discrepancies, please comment!
