approach

From a young age, I had always wanted to get a tower crane toy, but they are very expensive and complicated. When I got a 3D printer, I decided that creating my dream toy would be one of my first projects. I set out designing a crane that would have a small number of parts and would not only function well in play, but would 3D print without any failures. After many hours of iterating on the design, I had a final version of the crane. 

solution

I created a modular 7 piece design of a tower crane that can be expanded when needed. 

Failed tower crane print from earlier iteration.
