This is a CPL filter mount for the blueskysea B1W dashcam.

This mount press fits into the lens housing of the b1w with just your hands, the cpl filter also press fits inside. No glue, no mess.

You will need the CPL filter for the A119 dashcam. Its ~ $14 and can be found on amazon.

Press fit the mount onto the B1W dash cam lens housing making sure to line up the raised notch to be at 12 o'clock or 6pm (top or bottom) (you'll see why below).

Take the glass filter out of the plastic housing it originally came in (making sure to mark the bottom or top of the glass before hand to maintain proper polarity angle). Press fit the cpl filter into the mount making sure to line up the marked part of the glass with the raised notch on the mount.

Make sure to wipe with microfiber or glass friendly cloth so that there aren't smudges or particles on the cpl filter before pressing in.

I only tested with PETG. This will be on a hot camera in a hot car, Dont use PLA. ABS will shrink so there is no guarantee the press fit tolerances will be correct.

I recommend PETG.
