Ball End Hooks for Gazebo Curtains or Net

A friends request to adapt a curtain hook, with a tiny bit of streghtening of the connection between the ball end and the hook. Original design is said to be fragile and break quite often, additionally being hardly available as replacements, so there you go!

How to print?

To make it printable and easy to assemble, model consists of two connected halves, which must be glued together. 
Should be printed at least with PET-G, prefferably ASA or other heat-resistant material. Prefferably use 4-5 walls to keep a bit of flexibility and 4 bottom layers to make them tough enough in the middle part.
Consider using Variable layer height for better finish on the ball.
