Picatinny (NATO) Rail flashlight mount

thingiverse

This mount was designed to fit a cheap chinese flashlight that I presume is available under various brand names. Mine is branded "LCYYO" and came 2-for $13, I like this flashlight because it's zoomable LED, feels durable, and most importantly, it has an insert inside that takes 3x AAA batteries that are available anywhere. No worrying about your boutique batteries dying and having to search for replacements. The most important dimension of the flashlight is the diameter of the recessed area on the tube. It should be 26-27mm. I've included the fusion 360 source file and a step file so you can remix this to fit your flashlight. #BOM * [1x 35mm m3 bolt](https://www.amazon.com/dp/B07VRC6DHD/ref=cm_sw_r_tw_dp_x_aWVeFb86C3A53) * [1x m3 nut](https://www.amazon.com/dp/B07VRC6DHD/ref=cm_sw_r_tw_dp_x_aWVeFb86C3A53) * [2x Standard Zip Ties](https://www.amazon.com/dp/B086RQMF88/ref=cm_sw_r_tw_dp_x_fVVeFbADEVEXA) * [1x Chinese LED flashlight.](https://www.amazon.com/dp/B07WFFWT6G/ref=cm_sw_r_tw_dp_x_ePVeFbBSB79MA) #Assembly 1. Thread the m3 nut and bolt together by a couple milimeters 1. Holding onto the bolt, arrange the the m3 nut into the hexagonal hole in the back of the mount's mouth 1. you may want to add a small drop of super glue to the hutto make it easier to register the bolt when you thread it back the other side 1. Unscrew the bolt leaving the nut 1. insert the flashlight the mouth of the holder at it's forward-most recessed ring on the barrel which measures ~26.5mm in diameter. 1. For a fully secure fit, insert a zip-tie into each of the two slots, smooth-side up. Wrap the tails around the barrel of the light and secure the zip ties. 1. Slide the profile over a pic rail of your choosing 1. once it's close to it's final position insert the m3 bolt from the back side and thread the nut on the opposite side. 1. move the mount forward in the rail until your bolt is touching the rail. 1. Snug up the bolt. You may choose to use loctite, but the metal on plastic interface seems to hold bolts in place fairly well.
