Cokin P filter to 4x4 filter adapter plate

This little adapter plate allows you to snap in a Cokin P filter and use it as a 4x4 filter for your matte boxes. This is so you can either start, or expand your filter selection on the cheap.

Sketchup file included for anyone wanting to modify.

Instructions

Recommend printing in black PLA or ABS to minimize stray light reflection in your matte box. Print with support material, then snap in your filter!
