Hi!
I wan't to share my Robot Arm design with you guys. It's 3D printed and all parts (STL) and an assembly manual can be found on our github. It's the third iteration of my initial design, and it comes out quite nice now. I also spent quite some time on the assembly manual, to make it easy for people to assemble.

To read more about the arm and for links to github, a video and more see:

Best regards,
Mogens
