I finally got around to making some of the needed modifications to my previous triple axis tourbillon design (https://www.thingiverse.com/thing:2090912). Check it out for the listing of non-printed components (with links) and a brief and highly suspect lesson in horology.
Improvements include the following:
- Fork now includes a guard pin for increased reliability.
- Flats cut into shafts. The previous version relied on friction, so parts wore out very quickly.
- Improved ball race without an insertion hole. No more airsoft pellets making bids for freedom.
- Added gear teeth to the ball race in case I want to make it weight powered at some point.
I still want to add on a system to power it with weights rather than fingers.
