For a flashlight that could be paid for with pocket change, the quality on this is stunning. I didn't do much to modify it at all, only grinded the end a bit and re-did the surface finish.

After making the copper heatsink for the M462, I had to rig this up to be 3D printed:


Mind you, the bolt and nut weren't printed only the plastic part. I actually had to grind the nut smaller to prevent it from shorting to the host.

After e-poxying, here's the final product! :D





The M462 diode is in a 12mm module along with the boost driver, set at 1A for roughly 1W of output power. The divergence works out to be really nice with the 3E lens too.

Thanks for reading!!
