Gears were designed with exactly 27.5mm center distance.

Petal iterations addded a chamfered edge to allow one to sldie beneath the other.

|
Initially had a slide guide for the petals. However, upon first print, the guides were too small to be useful and the regular design worked well enough to disregard them.
|
|
|
|
Completed FEA on the whole system, putting 5N of drag on each petal.
|
|
After analyzing the results, I added a chamfer to the bottom edge of the petal where the flat drag portion connects to the gear.

Actually printed. The petals had to be scaled down 98% and the center gear was scaled down 95% because the gears were too large and were put in too much compression. |
