This is my 100% 3d printed tourbillon model it has no metal parts and uses only PLA. It can run off the stock spring for about 1:20, and it even self starting is assembled correctly.

Instead of given dimensions and stuff so you can use it in your own stuff here's the source files available for free off Gum Road (Fusion 360): https://app.gumroad.com/25cogs#OsKSd

All of these parts are printed in normal PLA you will want to make sure that you have your E-step and flow rate set correctly as the tolerances are very tight, I highly recommend you freshly level your print bed. As far as settings go you will want to print these parts with movement speed turned down to prevent blobbing on corners, and leave support material on but very few parts will need it as all parts can be made to sit flat on the build plate.

You will want to print the following parts at .1 layer height, 6 wall lines, no infill needed.

These other parts can be printed at whatever setting you to want but I would still recommend them at .1
