I wanted to be able to mount my handheld Cloud Defensive MCH EDC light to my airsoft Picatinny rail. The mount is symmetrical and can be mounted on the left side, right side, up or down. I printed mine in Polymaker PLA Pro, but can be printed in tougher or more heat-resistant materials. The mount only requires 3x m4 nuts and bolts, and prints in just two pieces, the latch for the light prints in place.
