Raspberry pi Camera - Focus ring

I designed this focus ring that you can super glue to your raspberry pi camera. It allows you to easily focus the manual focus lens.

IMPORTANT:
Make sure you just put a bit of glue on the top of the pi camera lens on the outside (not near the lens opening). You have to make sure that when your press the focus ring on the lens, no glue is being sqeezed out into the lens opening.
