Bird feeder (again)

OK, maybe I'm obscessed with this thing. It's probably time to move on....
The last version corrected the weakness, but there was still an issue with rain. How did I miss the fact that if I made the base so it curved upwards towards the bottle, water would penetrate less.
This new design provides a lift of 8mm between the outer part of the rim and the centre. This along with the umbrella means that I haven't had to unclog my feeders for months.
The 3mf file works on a Prusa slicer, but not in Cura - I don't think the latter has the features being called up here. Please advise me if I'm wrong.
The umbrella stl file should be rotated to print it vertically, with supports on, and you should enforce supports for at least the first 50 to 100 layers
And enjoy - the birds in my garden love it.
