Thingiverse
A robot inspired by the 'iron giant' made for an intro CAD class. Printing of individual components is recommended as the orientations can be optimized and the arms will be able to rotate. The full model is also available for download, but will require the generation of support to print properly. The fingers on the normal arm will not print well without upscaling the model (it's currently about 6 cm in height) but two cannons are cooler, anyway.
