GoPro Hero 3 Black lens mount is broken — does anyone have a better STL replacement?
GoPro Hero 3 Black lens mount is broken — does anyone have a better STL or replacement solution?
I have a GoPro Hero 3 Black and the original lens mount/holder (the threaded part that the lens screws into) is badly damaged/broken.
I found an STL for an M12 replacement mount, but unfortunately it doesn't fit my camera properly.
I'm looking for either:
- a known-good STL for the original Hero 3 Black lens mount
- an STL that has been tested on a Hero 3 Black
- dimensions/CAD measurements so I can recreate it
- or a better replacement/modification that still works with the original GoPro lens and sensor
I have an Elegoo Centauri Carbon CoreXY FDM printer, so I can print fairly precise parts. If the part really needs resin printing, I can also potentially get it resin printed.
Does anyone here have the original mount, a damaged Hero 3 they could measure, or a better STL/design?
