This model might be kinda niche.
I modeled wall mounts for the fairy wings of my fiancée.
She bought them for photo shoots and (cosplay) conventions among other things.
As they're massive and it would be sad to lay them under the bed and let them collect dust - they're now hanging on the wall.

The wall mounts are modeled so it would be possible to mount the wings on a sloped roof. With the little clamps you can tie them down, so the tips don't slant down over time.

For the smaller wings we didn't use them, but for the bigger wings we mounted 2 clamps (see picture).

We just used double sided tape to stick them to the wall as the wings are only ~1kg each.

Wings were bought from:
