The pictures show that the ball socket joints are in a 90 degree orientation, but the print files are for straight oriented ball socket joints.

Very cool project! Is there any video? Doesn't it get wonky after a while?

You could also MAKE your ball joints...

I will try to make this kit for use on a quadcopter using FC as servo controller. Thanks for your brilliant creation.

Sherical rod end (Traxxas)

I'm not quite sure how you join from the push-rods into the bracket at the camera end, and can't see it clearly in the photos? Also, what's a "Ball joint cub" - is that just a typo?

I don't get the questions.
The last picture shows the mounting methode on the camera side.
A Ball joint cub is the cub where the ball fits into.(look at the STL files)

Thanks for answering so quickly! I've looked at all the photos, but I'm not clear from that last photo. I've only seen ball joints with through-holes before, but it looks like those balls have built in threads? Are they just threaded directly into the plastic of the Bracket.stl part?

"A Ball joint cub is the cub where the ball fits into" - do you mean cup? Google doesn't know what a Ball joint cub is...

Yes the balls have build in threads and are threaded into bracket.stl
It is a typo indeed. cub = cup

Ah cool - thanks! I'll post photos when I finish putting it together - building the linkages are the last part.

I just made one (see the pics in "I made one" :) ).

Could you post the source in a form editable by an open-source 3D tool? .scad or .csg, preferably.

I could easily redo most of the design in openscad, but I can't hope to replicate how perfect the ball joint is without a lot of experimentation. What are the exact dimensions?

The camera I have is a lot smaller, so I'll have to redo the mounting plate, and metric screws are expensive in the USA, so I'd like to redo the holes for what's available here.

Also, not clear from the pictures is how the pushrods attach to the servo and the plate's bellcrank. Are these standard RC-model parts?

Thanks.

Thanks for printing my project.
I added the .STEP file and two more pictures.
I had to borrow the servo's for a different project so they are currently missing.

It works side to side when both servo's are operated opposite to each other.
So one is moving forward and the other is moving backwards.

And it works up and down when both servo's are moving in the same direction.
So when both are moving forward the camera is going up and when both are moving backward the camera is going down.

Hopefully this answers your question.

Am I correct that this only pans the camera in one dimension, side-to-side? Or can it till up-and-down too?
