Updated: https://www.thingiverse.com/thing:2370513 Electric controll upgrade kit for this design.
This is the V4.0 of my slider design which is smaller lighter to carry, foldable gear, smooth bearing on lathed wheels. If you like and you are a videomaker then print it, let me know. That's good to collect this project or like it.
Finally, all the information are in the instruction.download the pdf file, there are just a few steps to teach you how to make one slider pro and that's 3D printed indeed.
This is V2.0:http://www.thingiverse.com/thing:1767771,and V1.0:http://www.thingiverse.com/thing:1637418. Or you can check other design of my camera stuff
And I need a help, my third version, I need help for the software control, just a stepper motor, so I can make it live, anyone can do me a favor send me a email in thingiverse, great thanks.
