Bird Feeder Refill Funnel

My girlfriend wanted a way to easily refill our bird feeders without the hassle of taking them down or removing the lids every time. I designed this funnel specifically to solve that problem. It fits perfectly into common bird feeders constructed from clear pipes with an 87mm outer diameter.

My prototype has already lasted a whole winter long with no signs of aging.

Print Instructions

• Orientation: Print upside down (wide part on the build plate).

• Supports: None required.

• Material: PLA works great (I used Extrudr NX2 Yellow). I guess PETG would work too.

• Nozzle: 0.6mm (0.4mm will also work fine)

• Layer Height: 0.3mm
