"Spring" for Biting T-Rex

We simply loved the Biting T-Rex by @Myron_Yuskovych , link to the model down below! We were unable to source the spring in a timely fashion so we decided to try our hand at modeling one. We imported the T-Rex head and lower jaw into Fusion and started tinkering. After a hand full of trials we landed on this design. It will not close the jaw all the way like a spring would, but it will keep just enough clamp force so the little guys can nibble on a finger or any other object! Capable of supporting the dino's weight while suspended and chewing on a bone (link below), this is a good alternative to needing to purchase a spring. This design is likely to evolve as we find weak points, it has been subjected to some ad-hoc stress testing already but I am sure something is bound to break. Please let me know what suggestions you have and I will work to bake them in! Printed at 100% infill for strength, this only took about 13 minutes on the X1C and the majority of the time was bed leveling and
