Here is an example application, I am working on this part in the CAD program
This is a work in progress I add something now and then as I can get the time. The next step is to add the motor (create the mounting holes and make sure the motor gear fits well.
I made these images just to show one way to mount the slip ring.
Here are some example designs on Thingiverse using slip rings see Things tagged with Slip Ring
