My 10 year old was teaching me how to use Tinkercad and everything he learned in school. I let him mess with the program for about and hour and this castle is what he came up with. Blew my mind i've only been 3D printing myself for about two weeks now.

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/8yGuuH8wt4Q
