Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
This is a 3D printed robotic arm
The intent was to design something "easy" and cheap to built with a good visual impact also.

I spent time to look around the web at some examples available that could be a good starting from, and between all I found interesting the phenoptix MeArm V4 project (http://www.thingiverse.com/thing:360108) especially for the simplicity and low cost of parts involved.
So I kept only the kinematics geometry and redesign all parts including the gripper
