HUH WAT WUD U DO IF U HAD ONE? For those that don't know a 3d printer is like a normal printer but prints out like 3d models. I'd make all kinds of crazy shit and bring it to school and be like LOL LOOK SOMEONE MADE A TOY OF THIS WTFFFF!!!!!
I would design my own twisty puzzles, as is one of my hobbies. I cube, as in, solving the rubik's cube really,really fast. Go on youtube and type in "petaminx", that's a custom printed puzzle. Warning, you will shitbrix upon seeing the video.
