This is my first transformer design. It should print fully assembled and ready for transformation. Right now he's pretty small, so I'm not sure how well he will scale up. I just did a 0.3mm print with 20% infill. On the plus side, by default, he took me about 30 minutes to print. So you could have your very own transformer in the time it would take you to run to the store and buy one! :D Once finished, gently remove him from the bed, and slowly work out the arms, legs, and feet.
