Robotic arm

Disclaimer this is not my design credit goes to krzysztof over at Zortrax sharing platform. Just thought it might get more love over here. I haven't printed this yet but plan to. If any one has any tips or suggestions please do tell. I would like a different claw on this arm, so if some one could help with this that would be great. I don't know if it will work or how great it will be but it does look promising. I did not find any assembly instructions so this is all I have to go by.


list of parts:
1. Nema 17 – 5pcs
2. SKF 625 – 4pcs
3. DIN 6912 (M4x16) – 42pcs
4. Steel Balls – 5mm diamater
WARNING:
You need to maximize every item to 1000%
I think it will work
