Mechanical Robotic Arm 4 Claw correct version 3D print model

This is mechanical robot arm with 4 claw. It uses the Screw mechanism to open close. I made a robot project using this exact model. the parts can be cut using laser cutters or cns machines. This is compatible with any type of pick and place robots. you can 3D print any part and use it. Also if you need more strength then you can use carbon fiber to make it. If you need any simple modifications let me know. I will try to do it for you.
