The Tourbillon Mechanica is an almost entirely 3D printed functional mechanical clock (except for metal pins and screws)
This skeletonized mechanical clock with a tourbillon escapement is designed to showcase a basic mechanical watch's mechanism. It has a unique hour and minute indicator that runs around the perimeter in order to showcase the entire mechanism.

I received many requests on whether or not the Base (The largest single piece part) can be fitted onto some printers with slightly smaller rated build volume. There is a new split base and ring gear option that only requires a 160 x 110mm build area to print the entire model. The base and ring gear files can be downloaded for free as a fit check here.

Sheet Spring Steel for mainspring : Link (Optional as I highly recommend using the 3D printed PETG spring)
Update Oct 09, 2021
Design Update:
- 10_Base_Split : Added split base option to reduce minimum printer bed size requirement significantly to 160 x 110mm
- 13_Ring_Gear_Split : Added split Ring gear option to reduce minimum printer bed size requirement
Assembly Guide Update:
- Page 3 : updated min print bed requirement from 220x220mm to 160x110mm
- Page 4-5 : added split base and ring gear assembly details
Update Dec 6, 2020
Added Step file of Base for those who wanted to try modifying it to fit smaller print beds. Step file can also be downloaded for free in the link above
Update Oct 27, 2020
Added 2 new files:
07_Hairspring_Thin - Thinner hairspring to provide more headroom for frequency adjustment.
45_Tourbillon_Ring_Gear_Larger_OD: Received some feedback that ring gear is too loosely fitted to the Base. Modified with larger 0.8mm larger OD for a tighter fit, increased clearance between runner gear and ring gear for smoother meshing.
Update Sep 13, 2020
Added the Escapement mechanism explanation in the assembly guide.
Added a Stp file of the escape fork for those who want to optimize the performance further.
Added a "safe" escape fork design (03_Escape_Fork_Reduced) that should be able to cater to more significant variations in assembly, printer setup, print settings, etc. (I recommend those who had issues with the mechanism slipping and jamming to give this version a try)
Added high res assembly guide in the download zip.
Fixed some minor details in the runner gear and Tourbillon cage bottom files.
Fixed some qty errors in the assembly guide.
Update Sep 8, 2020
Added Display stand and winding key! Apologies for the long wait to those who requested. Do download the latest zip file dated (08Sept).
I would highly advise downloading and reading the printing and assembly guide before deciding to purchase the file.

The escapement mechanism is the most intricate and print-setting sensitive part of the mechanism. You can download it for free here to see if you could print and assemble that part before purchasing everything.
.3mf files are also provided for those who want to reference the settings that I used. Please note that you will most likely be required to tweak some settings further since every printer has a slightly different setup.
For Prusa Mk3/s Owners, thanks to fellow maker: Marius Tulbure
It is possible to print the base on the 250x210 rated build size by setting the plate at 250x216 in your slicer setting and moving the starting point at 0, -3; the last 6mm are printed on the wiping area. You need to remove the skirt as well.
The addition of split base and ring gear option (can be downloaded for free here) allows the use of much smaller print bed sizes, as small as 160 x 110mm to print the entire model.
