Battle Arms Development really created a “Bad ASS” design with their ambi-safety systems. Taking it a step further for those who want to print at home, user Down0047 has posted up 3-D CAD files of the system allowing users to design and print their own selectors. 

I am especially a fan of this, as those who like to experiment and design their own levers now have a solid and proven base to print their levers for. Of course, the selector would be a plastic, so these home-printed kits would not be as durable as their metallic cousins.

*Author’s Note: Don’t pirate someone’s copyrighted and patented works. Ensure any usage of these files is for your personal enjoyment in creating novel levers for your personal usage. I have personally tried 3-D printed safety/selector components at work and they will NOT stand up to tactical abuse.
