Bottle Cap Bird Feeder

I Designed this bird feeder to fit the bottle cap thread I usually have.

No Supports needed.

Bottle thread Ø 26.40 mm [1.04 in]
pitch 2 mm

[24.08.22 update]

I added a version with a different thread as asked by Buggi
that fits on some german bottle cap.

Also added thread pitch as a name suffix
The original thread was Ø 26.40 mm, pitch 2 mm [suffix p2]
The new thread is Ø 27.5 mm, pitch 3.18 mm [suffix p3]

feel free to ask for a different thread
I will be happy to prepare it, 
if I get a chance and time to do it.
