This is a 3d printed camera slider that I've beeen working on for quite some time. As of now it's only manual but in the future I'll add a motorized version that uses the same parts as well as some extra ones so if you want that you can print this eather way.

If you want to see it in action I've made this video: https://www.youtube.com/watch?v=WX7g5iMNASM

And if you want to build it yourself you can watch this build guide:

You only need to print one of each of the models.
You also need:

4 m5 t nuts
9 m5 nuts

4 m5x12mm bolts
7 m5x30 hex head bolts
1 m5x40mm bolt
5 m5x30 bolts
1 m5x25 bolt

4 v slot wheels
2 6mm spacers
2 6mm eccentric spacers

For the camera mount and the links I used the ones from the modular mounting system. You can download them here: https://www.thingiverse.com/thing:2194278

You can as any questions that you want and I'll try to answer them both on the video, my mail 3dprinting.3drcnc@gmail.com and here in the coments.

Happy printing!

Nothing special. It should be fine with pretty much any settings but this is what I used and it was really ridgid so it seemed to work well. Only some parts require supports such as the direction changer .
