Samsung Gear 360 base mount printed in flexible. Recess and hole in base centre for tripod type screw and six holes around the rim for 6mm neodymium magnets. Useful for temporarily fitting to a car roof for example.
Blender units tend to not play well with others - if using Cura try scaling to 1000%
I printed without supports which left a mess underneath but this was probably easier to cleanup than removing supports, is in a normally hidden spot and doesn't effect it's structural strength so it's dealers choice.
Originally I used 40% infil and 0.6mm walls but wasn't happy with the bit of wobble this allowed (which I worried could oscillate and ultimately pull a magnet free and finally the whole thing.) So, I've thickened the 'neck' where the camera meets the base and then printed with 75% infil. This seems about right to me now. (It can easily support the camera at 90 degrees whilst still, but no guarantee implied! ;) )
