This is my little bee / bird trough which I've placed in our garden water barrel. This floating island also (hopefully) helps drowning insects.

Printing:

I designed it a little bit to big, so i printed it on a resolution of 75% (bigger wouldn't fit my bed).

Also i printed top, button and walls with 6 layers (to make it more water proof). I used 20% infill so that small air champers are created to let it better swim
