Flashlight Mount - Picatinny 19mm

thingiverse

I needed a mount to put on a new Ruger 10/22 Takedown I picked up to put a flashlight on it. I have some 4Sevens AA2 flashlights laying around and it seemed like a decent pairing. A weapon without a light a horrible mistaking waiting to happen in my opinion. This mount is for a flashlight that's roughly 19mm in diameter and only requires a single bolt to attach it and the light. The package includes various height / profile versions and two slanted versions. The slanted versions were necessary to offset the slant on the Ruger TD I have so that the light and barrel are in somewhat close alignment. Including them here in case anyone else does the same thing with their ruger and a AA2 or any light with a 19mm body. To mount it I just drilled two holes in the forearm and then put a Magpul MOE picatinny rail on it. You could very easily just print a picatinny rail and use that, I just have several Magpul rails laying around unused. This is basically a remix of mechpilotz' mount, I just shrunk the hole a bit to fit my light and then made it longer for a bit more surface area and adjusted the height, I wanted it as low profile as I could get. NOTE: I used PETG so that I can heat it up just enough to pop the light in as the 4Seven's AA light has larger diameter sections on both ends so there's no way to just slip it in. On the plus side there's no way to lose your light unless you lose the mount as well. With PETG I'm fairly positive you'd have to destroy the forearm before the mount breaks off. Print Settings Printer: MendelMax 3 Rafts: No Supports: No Resolution: 0.25 Infill: 20% Notes: I printed in PETG for more strength than PLA and less noxiousness than ABS. I find PETG pretty easy to work with on my MM3. And frankly I'm not sure I could heat up either one and get my specific light inside the mount without warping it or breaking it. Using eSun's black PETG I print at 60mm/s, 245C extruder temp, 60C bed temp, bed is covered in 3DEez. No issues to report. Post-Printing To get your light into the mount just heat it up with a heat gun or hair dryer along the top curve and it'll flex enough to get the light in. Doesn't take a lot of heat to make it doable. An M5x35 bolt and nylock nut fits perfectly in the mount for attaching.
