3D Printed Flying Tourbillon Assembly

All parts are printed from PLA, except five (5) of 4.5mm steel balls for 608 bearing. Even the pins were strands of 1.75mm PLA filament. The entire mechanism is powered by a spring printed in PLA.
3D printed design is modified from the Flying Tourbillon Model 1.5 by A26 at Thingiverse.
The frame joints are modified from hexgon snap in type to screw type. So the model strength doesn't highly on the 3D printer's tolerance, and the frames are durable.
The main spring case is redesigned stronger. It can always hold the main spring in the center. Also the center hole is providing the second support point, so the tourbillon frame (black) has totally two support points, 608 bearing and main spring case. The tourbillon can rotate in a better straight position. The tourbillon frame is also extended to fit into the hole on main spring case.
