I have many ND filter from my GoPro 6 and 7 and from Telesin, this one from the link http://tiny.cc/y0dluz

And I wanted to use them with my new GEPRC naked GoPro. They are not directly compatible but with this little adapter you can keep using them.

Print it in TPU, put it around the lens of the Naked GoPro and then put your Telesin ND filter on top. The fit is tight, and I have tested a couple of "hard landing" and the filter stays put.
