509 Altitude 2.0 Helmet Chin Mount for GoPro

Before 3-D printing, I purchased something similar from chinmounts.com. It was high-quality and fit perfectly, but I wanted to try and create one myself. The chin mount version is probably a much higher quality, but this seems to work just fine.  

I modeled it after a 509 Motorcycle/snowmobile Altitude 2.0 helmet, but it may work on others.

I have included the stl file so you can upload it to TinkerCad and tweak the arms a little to fit other helmets.
