Bird Feeder Lid

So the lid of one of my bird nut feeders turned into a rusted mess and rather than go out and buy another one, when the rest of it was fine, I made this.

You'll probably want to use the scad and adjust the 'plug' value for a snug fit in the feeder.

Print in TPU - I used Flashprint fast setting but pretty much anything should work as long as it's TPU.
