Bird Silhouette Wall Hangers

I saw some of these hooks on Etsy and they were made out of metal. I figured in try to recreate them and 3d print them. They are a cute addition to any wall. They are functional wall hooks but are extremely subtle, the hooks aren't really that noticeable. These are printed flat without any supports, however the print orientation makes the hooks weaker due to the layer lines. I tried to beef them up as much as I could but I am quite new to 3d design. They should hold up to most lighter jackets.

These were printed with 15% infill as they were more of a test print. I not sure if beefing up the infill will help with the strength due to the orientation of the layer lines. If you have any design suggestions, I am all ears!

Thanks and enjoy!
