This is a custom-designed 3D printable helmet mount for the Sony HDR-AS20 action camera in its waterproof housing. The mount consists of three separate parts, each provided as an individual STL file. These components are designed to be printed individually and then assembled using standard hardware. The model has been successfully printed using PLA filament on a homemade 3D printer, and the assembled mount has been tested in real-world use, mounted on a motorcycle helmet during actual rides. It provides a secure and stable attachment on curved helmet surfaces, making it perfect for action and outdoor filming. The parts are designed for easy printing on most FDM printers without the need for supports.

Included Files:

3 × STL files (individual printable parts of the mount)
