I ride with a pro-tec style helmet and couldn't figure out how to mount my magicshine mj-880 to it with the supplied helmet mount other than using velcro. I didn't think velcro would be strong enough so I decided to try and make a custom mount using an extra go pro mount I had. I work at a dental lab making fake teeth so I have access to different types of acrylics, so went about making one using essentially the "lost wax" casting type of process. Here is how it turned out.
First I made a model of the bottom of the light out of stone after using a silicon duplicating material. Then just waxed up what the mount would look like and made sure it fit the go pro mount.
Then I invested the waxed up mount in a duplicating material and boiled the wax away and poured it up using a clear dental acrylic.
It took some grinding to get it to fit the little tabs on the light but after a while got it to fit. Seems strong, and I can adjust the light up and down so that it still hits the trail the way I want it too.
