GoPro Click-on camera mount for Fox Proframe MTB helmet

thingiverse

I didn't like the upside-down camera mounts for the GoPro, some with a J-hook, some attached to the visor of the helmet and some to the chin of the helmet. All glue-ed or with double-sided adhesive tape attached to the helmet. Why is there no click-on mount ? So I made one for the Fox Proframe MTB helmet. Well it is named chin-mount but it is closer to your nose... nose-mount ? My helmet is a size L !!! I don't know if the chin-mount will fit different sizes. My advise: print the MountSimple first and check if it fits the camera. It requires only some light sanding and clearing of the 5 mm hole. If needed resize it in the slicer and try again until you find the correct resize percentage which you can then use to print the ChinMount. The mount is printed in PETG on a Creality CR-10 with 0.2 mm layer height (does work with 0.3 as well). Support is blocked almost completely. I only use support for the small area under the cap nut !!! Use a print-temperature and print-speed that results in maximum bonding of the layers. Because it is a click-on mount maximum strength is needed. This is also why I use 100% infill and print at low speed (30 mm/s), printed at 257 degrees Celsius (Filament 123) with the heatbed at 80 degrees Celsius. I use a 8 mm wide brim for better attachment to the heatbed. Printing with solid colors (white, black) seems to deliver a tighter fit to the helmet as transparent colors do. Glue is NOT needed for the cap nut. The cap nut is heated before its pulled into its position with the help of a threaded rod (5mm). When it is pulled in position then cool the nut with water and unscrew the thread. The mount can be secured to the helmet with 1 or 2 cable tie(s), you never know... The mount is attached to the helmet is sits tight and does not move at all, there is no play. https://youtu.be/4UglJQ9h_A4 ChinMount_1_4 has the Hero in the upside down position.
