Eye Exercise Trainer

I was told by my eye doctor that this might help to get my eyes working together.
Now, I am not a doctor. I do not guarantee that this will work.

This needs a Large Format Printer as it is about 320 mm in diameter
Parts:
608ZC3 roller skate bearing
8 mm threaded shaft with nut (or 5/16" with nut)
cardboard to mount yellow disk, black strip, and red dot.
glue to attach to cardboard.
(you can see the glue thru the yellow circle- oh well!)
You need 4 of the Frame Clips.

All you do is spin it and focus on different parts as it is spinning. I made this so I can change the design to another that was suggested to me. That one is still a work in progress.
I also put in a nut slot in the handle, but it is not necessary as the treaded rod is screwed into the handle.

Does it work? Not sure, maybe? The jury is still out on that one. But maybe it will help you.
Print at your own risk!
