I needed a Drain filter for small gutter which prevents small maple seeds getting in a rainwater reservoir.

The half sphere itself I got from thingiverse Voronoi half sphere by JDanielAV - Thingiverse so all credits for this go to JDanielAV
(many thanks for this).

I added some base in bambu studio because it was easy doing (and I was in a hurry) and printed everything in PETG.

Came out great, just would have needed some supports for the middle of the dome, but in the gutter I don´t care for good looking of the inside of the sphere :).
