Here's my build of mcmaven's incredible model of the Jaeger-Lecoutre Gyrotourbillon!
I followed the instructions almost exactly, except I've used a 12V Stepper Motor and power the system through either a 3S LiPo battery or a 12V wall adapter. The stepper board then connects to the Vin and GND pins of the Arduino rather than the 5V pin. Using a potentiometer to play with speeds, I settled on a value of 250 on the stepper motor configuration.
I used SAE #2 x 3/8" flathead and round-head screws throughout the build. The screws holding the stepper motor were a little long and came up through the base, so I printed some 3mm tall stand-off washers to back them off a bit.
Instead of #4 lead shot, I used BBs to fill the counter-weight parts. This required some slight adjustments in my slicer since the BBs were just a little too large to fit into the counterweights, so the L1 pieces I scaled up to about 105% uniformly, and the L2 Counterweight I just scaled Z up to 14mm.
If you watch the video, in the timelapse of the Gryotourbillon running you'll notice that the model wanders around a little bit on the counter due to vibrations. I added a few drops of hot-glue to the base to act as feet which keeps things stable while it's running.
