Modular Bird Feeder Perch for Gazorpa’s Soda Bottle Feeder Base

I remixed Gazorpa's Soda Bottle Bird Feeder with this modular perch that would extend the diameter of the feeder to approximately 180mm. Tolerance is pretty tight so I suggest scaling a little larger, I used 102% and I dipped it in hot water before sliding it over the rim of the feeder base and quickly squeezing the outer and inner tabs together while the plastic cools. It should fit pretty snugly once it cools and hardens. Glue was not needed but a tiny drop should be enough to keep it securel
