Caged Tetrahedron Puzzle

This challenge will put your spatial skills to the test. The objective is to release the tetrahedron from its enclosure by using geometry principles that you hopefully grasped in class. Solution Video: https://youtu.be/t2j4Z-3CLDc You can opt for a nice wooden version available at http://amzn.to/2ztacMh. The green model was printed to exact specifications, while the purple one was scaled up by 50%. However, due to the limitations of my low-end 3D printer, I had to sand down the entrance of the purple model by about 0.03 inches to accommodate the tetrahedron. If you encounter a similar issue, it's recommended that you reprint the tetrahedron at a slightly smaller scale.
