Shutters top clip (brand Kwantum)

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5729168.

Clips to attach top part of shutters.

I found many variations online, but none of them fitted. These clips are for shutters bought at Kwantum shop in NLD.

First I printed some with PLA+, and that works. But PETG would be slightly better because it's stronger and wont bend when it needs removing.
