uStepper Robot Arm 4

This is the 4th generation of my Robot Arm design. It has been refined and is now easier to print, more durable and nice looking than ever!
Besides that I have spent a lot of time making a thorough assembly manual + a Kinematics document described on a reasonable level in quite a lot of detail. My aim is to make this Robot easy to print, easy to assemble, easy to understand the math for making it move and at the same time have a reasonable quality for students to use it.

To see a few more comments on the design have a look here:
