Murphy's law and that of Lift over Drag, aerodynamic force vs. printed layer adhesion strength.
The good news is they have gone 150 plus miles of spirited back woods road riding without letting go. So far, so good. Will be vigilant though.

Report: After several attempts at a 3D printed version of the fairing mount base, it seems the layer bond failure is more due to the mirror bouncing up and down over regular road bumps over time. The failure rate was just too high lasting 400 miles at the most before 3D print layer adhesion failure. I thought about going back in time and using the FJ1100 style handlebar type mounting like Maverick has.
Instead of that I got into foundry works using a lightweight 3D printed set as blanks for a Lost Wax type casting of a pair of handed aluminium mounts. If you want to know more specifics on the "Lost Wax" molding technique there is tons of information available through a Google search for that and reasonably priced equipment as well, in case you need another hobby to pursue and perfect.
Suffice it to say, I was able to produce a usable handed pair of aluminium mounts after a couple of initial manufacturing failures. One lesson is to make the spru and vents of your mold as big as you can so the molten aluminium flows without any restriction retaining most of its heat while pouring. Initial failures are ok while learning as the failures can easily be melted down again and recycled. I have not even had to tighten the stems up again after over 1500 miles now.
