Dual Planetary Gear Elastic Potential Energy

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2957207.

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. Inner planet gears will be fixed on shafts.

Second attempt using alternate gear module from Captive Planetary Gear Set: parametric. by terrym, originally from emmett's Gear Bearing.

Coming soon: base/top plate with shaft holes and assembled photos
