My roommate has the same helmet as me, but a different GoPro. The small session GoPro can easily be side mounted without catching too much wind, and with this mount, my roommate is still able to open the chin guard whilst filming. A luxury I don't have with the bigger camera and chin mount (I use the one that I've used to remix this model).
I had to simplify the mesh I got from the pack talk bold model, flip it and cut off the Cardo mounting part, then I just pasted the GoPro mounting on it.
Printing it hasn't been kind to me yet, I've tried printing it mostly upright to give a lot of strength to the GoPro mount and a bit of strength to the helmet mounting part, but the PETG I've been using is giving me lots and lots of stringing. After some clean up it's usable, luckily.
Update: I've updated the included gcode. Fixed the stringing for me completely and the print turned out spectacular
Would recommend printing it in a strong material as the helmet mounting part is quite small and can easily snap. During our last motorcycle vacation, the PLA printed version decided to melt en snap of on the road, not something you want I'd say
