The original mounting assembly (picture included) broke on my Wi-Fi bird feeder and no glues or epoxies I tried seemed to hold up.   So I made this little design that, while different, really does the trick to solve this weak spot in the design.  

I printed on my MK4 using 0.20 / 40% / PETG / Supports.   

I painted with plastic adhesion promotor spray and then white paint.   This should help reflect some UV and heat and allow the PETG to hold up for quite some time.
