Wind-up Dual Planetary Gear

Intended to replace a steel spring in a clockwork model.

Energy is stored in multiple rubber bands, on both sides, stretched between shafts through the outer ring and planet gears.

The central drive gear will be attached via some sort of ratchet mechanism to another drivetrain and escapement.

Untested idea. It might just end up being a paperweight or fidget device.

Note: minor design flaw, requires a fixed carrier for the inner planet gears (not included).

Edit: Playing around wit
