GoPro adjustable double mount

A single part that should be printed twice to work.
Connects two GoPro type cameras at a varying angle.
Use a nut and bolt (with washers) to lock the two arms together.
I use a longer 1/4 inch bolt mounted on a pole that also works as "stand" for the cameras.
Adjustable in 30° intervals and the FreeCAD file has all values parametric so you can change the number of "teeth" from 12 to something else, which will change the angle steps.
Also included my nut adjusting nobby thingies...
