Dive micro filter for GoPro

This is a dive micro filter which fits onto the fit still case like any other filters. It has a hole in the center to put a lens from any zoomable flash light. Best thing is, is that you can still use the light. You can scale it up or down to fit any GoPro case, and any lens. It works really well as a filter. I printed in 100% PLA. It is made for the fitstill hero 9,10,11,12 case.
