Lens cover for the standard GoPro 4 housing.

Tabs with negative draft has been added to ensure a secure fit when printed with a semi-rigid plastic material such as ABS.

Designed to work with ABS filament. I've compensated for some shrinkage (0.2mm bigger than the camera) but you might need to scale it up/down slightly depending on your printer.
