Here's another tourbillon model this time incorporating Ludwig Oeschlin's rather amazing Dual Ulysse escapement based off of Breuget's natural escapement. It uses a unique tooth profile so that the escape wheel teeth act as impulse and locking pallets in addition to powering each other. The disadvantages of this design are that it requires additional energy to overcome the inertia of two escape wheels and that it requires greater precision than comparable Swiss levers. This escapement may be found in the Freak series by Ulysse Nardin. I decided to throw together this design because I do not have $100,000 to spend on my mechanical toys.
This is an intermittently functioning prototype with PLA shafts as a proof of concept. Once my shaft stock arrives, I'll be able to more accurately assess its functionality.
UPDATE: non-printed parts are the following:
2mm steel shafts (amazon links in my other designs) cut to size based off of my PLA mockups.
One 607 bearing (size 22x8x7). Fit should be quite snug inside the base part.
1mm spacers (can be printed) go behind the escape wheels.
User animoose has a nice blender model attached in the comments section showing the assembled mechanism.
