#Shape Your World with 3D Printing I have been creating small autonomous self driving robots for the last 20 years. When I started out, the biggest challenge I faced was to build the mechanical parts of the robots. Even simple mechanisms need to be built precisely, which was hard with the tools I had available. With 3D printing, this is not the case. I can now easily make very complex designs, with several moving parts interacting with each other. The models below would not have been possible to make without 3D print. https://makerworld.com/en/models/207573 https://makerworld.com/en/models/207580 https://makerworld.com/en/models/207575
