GoPro to NVG Mount Adapter Bracket

• Note: This is a repost of an model from ~2016, availability of the external part has changed since then. Also, camera sizes have changed over the last decade.
• This is a GoPro style camera mount that securely mounts your camera to NVG helmet mounts to record your airsoft games or other adventures.
• Print in the orientations provided in the print profile - no supports are required. When assembled, the layer lines are oriented perpendicular to other parts, reinforcing the entire assembly making it very robust.

Components & Vitamins

• The main ‘vitamin’ component - formerly sold as an “Emerson” branded NVG mount adapter on Aliexpress.
  • The Emerson search term no longer seems to yield the component, however I found another source (non-affiliate link): https://www.aliexpress.com/item/1005004702246425.html
• You will also require a long stemmed M5 bolt, or a GoPro style bolt with M5 nylock nut to connect the camera to the adapter. Depending on your camera you may need to print a longer custom one.
• See the bill of materials for M3/M4 components.

Printing and Assembly

• Print in an impact-resistant plastic. You never know when you're going to bump into things when playing action sports.
• Assemble the body with the left/right plates as pictured. See bill of materials for the M3 components.
  • Note: this was designed for a GoPro Hero 3, if your camera is different, you may need to print the left and right plates mirrored, and assemble it mirrored. For my camera I wanted the bolt on my left to keep the right hand free at all times in case it needed to be tightened in the middle of gameplay.
• Mount the assembled parts to the NVG bracket mount using the M4 hardware specified in the bill of materials.
• Mount the NVG bracket to your helmet and check for fitment. You may need to make adjustments depending on your helmet.
  • If the M4 nuts on the back of the mount protrude too far and prevent the mount from clicking into the bracket, you may need to add space by re-mounting the bracket with a few washers as shims to give it a bit more room. Reproduction helmet mounts vary in quality and design tolerances, YMMV.
• Consider using shock cords to secure your GoPro if needed - I never needed it, but if your particular action sport playstyle is more vigorous (eg: speedsoft, paintball with sliding behind bunkers) you may require it.
