Bird Feeder Tray

I'm using an Apollo™ seed feeder on a garden pole and wanted a tray beneath to catch at least some of the seeds the birds drop. 

Using the maximum print size of my Anycubic Vyper I whipped up this design, that is a few centimeters wider, than the store bought version and comes at a fraction of the price.

I printed it in a Prusa PETG clear for a hopefully long use outdoors. 0,3 mm layer hight worked just fine.

Outer Ø = 24,5cm, Hole in the middle Ø = 2,4cm, so it should fit any feeder with a M20 screw/ thread at the bottom.
