>>10381713once you start doing VERY custom MOCing, you're no longer bonded to canon. make whatever the fuck you want. pic related was done with primitive methods, in a time 3D printing wasn't a common thing.
as for LEGO suing people's asses if they make 3d prints of official masks and stuff, it's probably because they're selling them for money and are openly public about it. it's best to keep it a low profile
