Geared version of ChaosCoreTech's "Powderpuff Unicorn", made by adapting the cube gear/cube heart openscad scripts.
This is on my "to-print" list for the next couple weeks, but I haven't actually printed this yet. Everything looks fine, but there's a couple skinny parts of the model which may or may not have enough strength to hold up to the rigors of being a geared object in a house with a 3yo and 5yo. Supports may be necessary on at least one of the pieces.
If you print this before me, please post a make and let me know how it goes!
