This robot was inspired by Cosmo from "The Electric State" It is not an exact copy of Cosmo obviously but he was the inspiration to make it. It is printed on the Kobra 3 Combo in PETG. Any filament will work. Recommend tree supports and be very careful during clean up or you may have to glue a few parts back on. The neck is a threaded rod that after printing is very springy. I did not make this as an articulated figurine. That will require some more refinement on the joints of the arms and legs. Still it is a fun print.
