This is my first attempt at a transforming action figure. The figure transforms from a Prius into a robot. The transformation process is easy but it could still use some modifications (such as hinges on the doors). For two color components, single and dual extruder files are included. Assembly: Most of the joints are ball joints that snap together. I recommend using glue to attach the head, driver front, and passenger front sections to the main body. Transformation tips: Move the arms towards the roof of the car and fold hands towards the front. Rotate legs 180° so the kneecap is towards the roof in vehicle mode.
