On the other hand, the amount of conventions I've been to and seen multiple 3D printed toy vendors in one venue, each sharing the majority of designs/prints among them, I can totally understand why someone would put a paywall for their designs.
I've seen so many identical flexi-dragons, "knitted" Pokemon, Mandalorian Mario characters, and fidget bullshit that none of it is unique anymore. Hell, toy companies have started selling those shitty 3D printed flexi-dragons on actual stores like Walmart because people actually buy that literal trash.
