I think 98% of 3D printers go towards printing trinkets for organization and figurines.

But I'm glad to be able to get into a 3D printer for an affordable price to do the other things. Probably wouldn't have happened without the mass(ish) market adoption.

Oh absolutely, I flatter myself to think I use them for "serious engineering", and I am well aware of my debt to Warhammer players who don't want to pay Games Workshop prices.
