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?
I would think that play would be difficult to keep low enough to make this worthwhile. A servo driven hot end is already pretty precise, so a pantograph-like transfer would have to be rigid and tight enough to beat that. No small feat.
Here's Stefan Gotteswinter giving a talk about his Deckel G1L pantograph engraver.[0] For the side load on a 3D printer it probably would work fine but as others have mentioned, 3D printers are already relatively precise. 0.04mm/step on my ender 3 as I recall. (about 1.5 thou)

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.
