I made this mount up so you can mount a gopro to your Fortis Titan frame and not drill any extra holes. The slots are 35MM center to center. Update: turns out the source file wasn't ideal so the spacing between the ams is a little to wide/the bolt hole isn't the same so i will adjust soon. In the meantime I just x-acto knife cut the bolt holes off and it fits perfectly. I hope to come up with a design that has a soft pad underneath to soak up the vibrations of flight. UPDATE: Added the "gopro_fortis_zip_tie_1" updated file. This one isn't as visually appealing and lacks the area to hold the nut which I will work on fixing soon but it gives a much lower mount if what your after is a VERY low profile mount to keep your COG down. Printed in XT filament at .2 layers, 25% fill and 235C, .8MM sides and 1mm top and bottom on my Ultimaker 2. Adjust settings per your printers requirements. XT or ABS preferred since PLA is a bit to stiff albeit you can print in PLA at your own risk!
