Hummingbird feeder that attaches to a mason jar (standard lid, not wide mouth). Used Printables @IanFoulds Mason Jar Ring for the threads and his awesome bird (seed) feeder as inspiration (see referenced models).

Pictured feeder utilizes Printables @Anachronist feeder flowers and @csubj ant moat. Printed in Hatchbox Metallic Red PLA, 10% infill, no support. I used a wall width of 3 to help make sure it is watertight. Will likely print in PETG or ABS if the PLA degrades too much in the sun.
