It is acceptable to epoxy, tape, or screw 3D printed components together and heads of the screws to be visible if they're only used for minimal support (i.e., attaching the top onto the sides of the robot, gluing 3D printed parts together at the seam if they'd be bigger than your print bed, etc.)
• Motors, electronics, axles, fasteners and adhesives can be any reasonable material but cannot be used in such a way to enhance the structural integrity, armor the robot, or enhance any weapon.
