This is a 3D printed robotic Arm.
It follows the success of my previous two designs: <a href="http://www.thingiverse.com/thing:1015238">EEZYbotARM</a> and <a href="https://www.thingiverse.com/thing:1454048">EEZYbotARM Mk2</a>
It has the same dimensions of the first one, so it is extremely cheap and fast to print only the main base requires a little bit more time to be printed.
This version was created with the willingness to replace the servo with economic stepper motors, and this is the result.
During development I found the stepper a little weak for the purpose, so I redesigned the transmissions on vertical arms, and apply a modification on stepper from unipolar to bipolar.
As the previous two arms it has been designed without a definite purpose, the aim is educational, providing a suitable hardware that allow to concentrate on exploring all its potential applications.
