To do that, you need to re-arrange components so that:
- ‘ArrPolar’ creates the fourteen blades and their gears, then
- ‘align’ rotation adjustments can be made on each gear separately without rotating its associated blade, then
- apply rotation from ‘inner circle main gear’ to all fourteen pairs of blades and gears.
But I’m concerned about the rather crude gears and the minimal rotation, which could have a lot of “play” between them. The end-to-end gear ratio here is 0.46, meaning the blades rotate slightly more than twice the angle of the driving ‘rotating bigger circle’ gear. Are gears needed at all or would linkages work better, with more precision?
As for gears in Grasshopper, I found a few references that might be helpful:
