Update 24. November 2014 Added a second version with an even higher angle. Which one to use depends on the hat and wether you wear it pulled down to your face or loosely. I used the basic clip shape, but flipped it around and made one side a bit thicker, so it would sit tighter (might give problems using PLA, I printed in ABS). I also used this Mobius mount: http://www.thingiverse.com/thing:340676 Just a bit of double sided tape and it will stick nicely to it. File down the nubs in front a little to keep it from holding the camera just a bit too tight. The idea was to let me film my quadcopters.. and since they're generally above me, the camera has to be angled upwards to actually catch the copter.Printed in ABS, no supports, 20% infill. Sliced with cura.
