Want to make a cheap robotic arm that's pretty accurate? You've found the right model!

To build the arm, you'll need:

• Arduino
• 3 ULN2003 Stepper Motors + Drivers ($3 each on Amazon!)
• 3 AS5600 Magnetic Encoders (optional)
• 3 10mm OD 5mm ID 4mm thickness bearings
• M2 Screws

and that's it!
 

An assembly .stp file is included to assist in assembly, and all included STL's have already been toleranced, so you shouldn't have any trouble getting them to fit together.

Please feel free to remix this design and make your own and share it!
