3D Tourbillon Clock Torque Modification

Many thanks to Christoph Laimer for sharing this incredible design.
This version has some modifications. I changed the gear ratio from the main spring so that more torque is applied to the system, at the expense of run time. The clock will run with very few turns of the main spring. If the spring is fully wound, it will cause the escapement to skip. I think over time as the main spring relaxes, it will provide a good balance of run time and torque.
I changed the ratchet pawl springs to provide more engagement.
I changed the winding key to a small knob intended to remain inserted.
I also changed the geometry of the screw holes to work with these screws from McMaster Carr:
95893A550, for ratchet pawls and clock face
95893A510, for tourbillon and going barrel
95893A560, for lower housing
