About this 3D model

At a friend's place, the thing that holds the cat flap in place on the litter box broke off. Instead of buying a new litter box, I quickly designed this thing. Just print it and glue it on - done! Printsettings: I Printed with 1.2 Layer high for perfekt results with such a small part. I Print it with 3 Layers then it is more stable.
