Summary This is an adapter that allows you to mount a Magicshine LED headlamp to the gopro mount included with a Giro EDIT helmet. It would probably work for most similar helmet mounts. This mount places the light higher and closer in than my original mount version: http://www.thingiverse.com/thing:197074 I use it for fatbiking at night, but it'll also work great for night skiing. I included the Solidworks 2013 .prt file for remixing.
