Please check the photos of the autopilots that this bracket is for!
This 3D printed replacement for the bracket is redesigned to be much stronger and printed in industrial strength plastic with a shiny smooth, glossy finish. Available in black (original colour) or white (nice on a fibreglass hull).
You'll notice this bracket does not have the rectangular holes through the bracket reproduced. Those holes were only there for injection molding the part, contributed to its breakage, and are not needed in 3D printing.
The original part number is D098. See the picture showing the control unit which this bracket works with.
