These are amazing. I could swear I've seen some of an horizontaly, not vertically, mounted pantorouter.

Since discovering the pantorouter for woodworking I always wondered: wouldn't the same technology make sense for ultra precise 3D printing at home? Instead of having the motors drive directly on top of the model, have the motors drive a pantorouter instead and have the smaller end of the pantorouter on top of the model. It's "just" simple machines right, lever and axle basically?

All I could find is people 3D printing parts to make a pantorouter for wood. But I'd really love to see one for finer 3D prints.
