Job ID: 32912145

Budget: $10 – $50 USD

I want to 3D print a 6DOF Robotic Arm and control it using arduino and NEMA-17 stepper motors with an interchangble head to use it with tools ex: pliers,screwdrivers. I want it very precise and compact size.
I just need the files to print them at 3D printing shops.
