Useful for mounting of Petzl LED torch onto a bicycle helmet. No need to glue on another mount if you already have a GoPro mount glued on. This replaces only the circular part of the Petzl Kit Adapt set. I made this for my dad - hopefully someone else finds it useful.

printed with 3 perimeters with 0.4mm nozzle at 0.2mm layer height in clear PETG. Infill probably not necessary. Position on print bed as in the rendered picture for best part strength.
