Multirotor Motor mount for 14mm tubes

Motor mount WIP
I will use it to mount two motors on a 14mm carbon fiber tube for a T6 or Y6 hexacopter built with 3 arms and 2 concentric motors per arm.

V2 changes:
-Rotated mounting holes 90° to route motor cables parallel to arm.
-Increased thickness of brackets to fit more common M3 screws
-added nuttraps on one side, to mount screws flush

Next changes will be:
-build single brackets to mount only one motor per arm. First design was meant to mount 2 concentric motors per ar
