Remixed the original for a better fit. Uses 2mm hardware, no need to go all the way through and use nuts. Printed mine out of GF Nylon. Will require supports now. Also remixed the GoPro mount. 

LED's and sensor are a tight fit. May need to drill out the holes a little for a better fit, I made them pretty tight for 2mm hardware. May fit 1.2mm Hardware with no modification.
