I need 3D model of micro servo with metal gears like the ones that came with the humanoid robot. I want to 3D-print dummy micro servos. I don't have the real micro servos. Also, I have problems 3D-printing some robot parts that require supports. Removing the supports leave rough surfaces on robot parts. I don't have the correct filament for supports. I have to go online and order micro servos, RGB LED Block, battery, charger, and filaments. I already ordered EZ-Brain Controller and Camera combo. Any suggestions?
