About this 3D model

Certainly not the first caliper case out there, but allow me to throw my hat in the ring with a design that I feel fills in most of the needs of the other designs, with all due respect to their creators! The Cylinder in the front is turn lock with the fingers on the side locking it into place, the little tower in front is just a custom support meant to be broken off after print. The mirrored clips near the hinges are meant ot hold spare batteries.
