ATN Night Spirit 2 Lens Cap and Retainer

thingiverse

This is a replacement lens cap and lens cap retainer specifically designed for an ATN Night Spirit 2 night vision monocular. I carefully modeled the holes on the retainer and cap to use 1/8" shock cord to secure them together in place. The lens retainer is engineered to be held firmly on with one or more zip ties that fit snugly into the recess. Additionally, the retainer is split at the top, allowing you to easily spread the ring apart to slide it over the body of the device. It's highly recommended to test print at low infill to verify fitment, as the tolerances are small and require a precise fit on the device. UPDATE: December 03, 2018 - I enlarged the holes on both the cap and retainer to make them easier to thread the shock cord through. I also added a V2 version of the cap with more rounded edges, and a V3 version with much more angular sides. UPDATE: December 04, 2018 - I added a V2 version of the retaining ring with reinforcements around the holes for the shock cords.
