3D model description

Small and compact windup tourbillon design based on the Blancpain Tourbillon Carrousel, less than a 100mm at its widest. I had to go through several design iterations and prototypes before i landed on a result i was happy with posting online.
It lasts about 3 minutes on 1 wind

Note: Mainspring must not be printed in PLA. PETG or ABS is preferred.
Parts may need to be reoriented before printing.

Tools and parts required:

A printer well calibrated for accuracy
0.25MM nozzle
Needle or diamond files
Cutting broaches, 1.5 to 3mm in size ( Example )
1x 688(ZZ) bearing (8x16x5)
2x MR63ZZ bearing (6x3x2.5)
5x M3 x 4MM screws (correct length is critical), preferably din 98 cheese head screws
4x M2 screws, max 8MM length
2MM metal rod
3MM metal rod (avoid piano wire if you only have light hand tools, that stuff is though)
Tool to cut metal rods
(optional) vision magnification
(optional) 1.6M x 4MM screw

Assembly:

Escapement:
Cut 2 pieces of the 2MM rod to a length of 17.5MM and 10.5MM (+0 -1 tolerance).
Press the 17.5MM rod into the escape wheel along with a bearing spacer.
Press the 10.5MM rod into the escape pallet along with a bearing spacer.
This should be an interference fit, use cutting broach if necessary.
Make sure that the metal rod sticks out by 2-2.5mm on both sides.

Frame:
Use cutting broach to enlarge the 2MM holes for the escapement on the mid and bottom frame til a running fit is achieved.
Press the 6MM bearings into their respective holes in the tourbillon frame.
Press the 16MM bearing into the stud on the bottom of the frame.
fitting a 1.6M screw to the regulator is optional, a light press fit with the hairspring stud works just as well.

Balance Wheel:
cut a piece of 3MM rod to a length of 22MM and press it into the balance wheel along with the balance wheel arbor/staff.
It is critical that the small notches on the the wheel and arbor/staff are lined up.
fit the hairspring to the small hexagonal part on the balance wheel, making sure the cutout. and notch are lined up to ensure orientation. (see pictures if you are confused)

Rejoice! the difficult part of the assembly is now over! and with it i will leave the rest of the assembly up to you. contact me on discord (Willie Fiddler#7397) if you need any more help.
