3D Tourbillon Clock Torque Modification

I have printed about 4 of these, trying to get a good running one. I FINALLY got it working.

My secrets:

  1. The main spring needs to be PETG to last more than a dozen windings. (PLA springs are too stiff, and deform only after a dozen cycles)
  2. THIS IS A BIG ONE: The static friction of PETG is MUCH more than PLA or ABS. When the spring is unwinding, the spring coils rub against each other. The spring is constantly starting and stopping with each tick, So its constantly overcoming the static friction - that REALLY messes up the escapement function. THE SOLUTION: cover all of the spring coils with graphite. PETG rubbing against PETG with graphite between them has MUCH lower static friction. I just used a pencil to cover both sides of the coils and it made a watch that ran only for a few seconds at a time to one that runs for several minutes at a time.

I wish it ran longer, but I finally got it. Thanks for the brilliant design, and thanks to Thingiverse for hosting it.

Hi, this is lit ! I love it
May I ask if you have the 3D step files please ?

HA HA HA! 404 likes! you do not exist!

Please specify dimebsions of the screws and pins. I have downloaded and printed all. I lived some problem about frágile pieces. Tourbillion Spring doesnt fit to tourbillion case front, breaks easily.

Hello...I have made the Clock according the STL`s from Christoph Laimer, but the force from the main spring seems to weak, it just runs for a few seconds.
Wich parts from your design are exactly necessary for more torque?
Could you make a part list for the modification from the original design to your design with more torque?
Thanks ;-)

in addition to the video already on the "Thing Details" page of this model, I would be interested in seeing a clip in which Christoph Laimer's original design and your remix of his were pictured side by side so we, those interested, can see the differences a lot more clearly, with his on the left and yours on the right; similar to those stupid Makeup ads on TV were they show you the 'before' and the heavily photoshopped 'after' (but the difference is we aren't shaming women into buying overpriced coloured dirt, we're looking at 3D Printed Clocks).
Thanks for the design.
:)

(The above comparison about Makeup was a satirical joke, all be it true.)

Is there a tutorial on how to create each part, not just download them pre made. Id love to go through making each part to practice with my program, and have an actual thing to print at the end. Thanks!

Alors là , vraiment excellent travail !
Je suis épaté !
Génial,

I really your colour scheme, which parts are what colours? Thanks!

Thanks! The materials are ColorFab PLA Sky Blue, Blue Grey, and Standard Black.
