I just got the urge to make a Retro style Robot. I had so much fun with this. This model is actually the result of learning how to use some new brushes.Suggested print size is 200% Thats what I printed mine at. If you have the space I would highly recommend printing him larger, just because I think he would be so cool if he was like 10 inches tall!I actually used PLA for the body and PETG for the arms. Just make sure that all of the stl's are laying on the flattest most side and it glues together perfectly!
