Hanging Basket / Macramee Hook for 8x50mm ring

This is a simple hook to hang up a ring with 8mm thickness and 50mm outer diameter to you ceiling. Rings with similar dimensions might also work. Its supposed to be used with a pan-head scrw with 8mm head diameter.
Step and Solidworks file is included, so you can easily adapt the design for your own needs.

The hook is designed so that the ring will hardly unhook by accident. I testes the hook with 20kg and it withstand that load without notacible deformation - printed with Prusament PETG and 100% infill. I suggest to rise the nozzle temperature a bit for stronger layer adhesion - this might make the part uglier, but it will be hardly visible at the ceiling anyway.

The print needs some supports. Support enforcers are included in the .3mf file.

Print the part laying on one side, so that layer adhesion doesn't influence the strength of the actual hook.
