Can consumer 3D printers pull off decent lego compatible parts? I'm fascinated by the idea of 3D printers, but I don't really have a good use-case to justify getting one. (And I've been waiting for them to come down in price.) I ended up getting my five year old the Lego "Boost" set - I wanted some motors &c that were accessible to him. He's had fun putting together the projects, and playing with the scratch programming. It is tied to their app, but I see that someone has python libraries to talk to it, so I have options if the app goes away.
