Skyrover X1 ND Filter

The way this works is that you remove the ND filter glass from the casing that is meant for the DJI Mini 4 Pro and you take that glass and put it in this 3D print. You have to be very careful taking the glass out of the original and ND filter. I used heat and my fingernail to pry around the edge of the front rim. In theory, this is reversible and you can put the filter back in the original frame, possibly with a little bit of adhesive.
