Cat Door Blocker

I Designed this model inspired by https://www.pngegg.com/fr/png-yngwn .

There are different models depending on the height of your door.

(3.2 to 7.4mm) (4 to 9.4mm) ( 4.8 to 11mm)

I printed it flat in PLA with 3 perimeters, 10% filling in grid with 0.2 layer height but 0.3 will be good
