This appears to me as the holy grail of 3D printing. Honestly.
Printed all parts and got the bearings and main spring. Need to rework the details and assemble it. Printed in PET. Struggled with the shape of the outer cage on my printer (Prusa i3 MK3). Maybe i re-print it in PLA. Small parts are fine with PET.
I suggest to get cheap bearings, as the high quality ones have a remarkable resistance when turning them. Just like as they were filled with thick grease. The high quality ones (ceramic, closed) are for sure better for Inline skates or skateboards. But for this gyrotourbillon the cheap ones might be the better choice.
Still need some extra time to understand the mechanics....
Great work of the designer !
