Bird feeder for small birds

This is yet another bird feeder.

I previously shared a design here: https://www.thingiverse.com/thing:4657703

It was meant to feed all kind of birds but the one I set in my garden has been privatized by wild green budgies, and smaller birds cannot get their share.

So I made this new feeder that is designed for smaller birds like blue tit birds (I happen to have a small nest of those).
It features a transparent PMMA tank and a wide feeding cup, but big birds cannot stand comfortably.
You can fill and refill the tank through a hole in the roof that can be sealed with a screwed cap.

Parts list:

• PETG for the plastic parts
• 2 x 160x85x3mm transparent PMMA boards for the front and back walls of the tank
• 2 x 69x85x3mm transparent PMMA boards for the sides of the tank
• 1 x 164x100x3mm transparent PMM board to extend the roof and protect the seeds
• 3 x 4mm M3 flat-head screws
• steel wire or some strong yet thin string of rope to attach the whole thing to a tree
