Printable earring hooks.
This is one of the most surprising thing I ever printed. I was sure it was going to be a failure but turns out they work very well! They are surprisingly durable.
I print them in PLA. So far no one had any bad reaction to them.
Given what PLA is made of I think its safer than ABS.
I did not use any special settings to print them, they are so thin that they come out full no matter what you do. I have a 0.35mm nozzle.
If the little rings are not split, cut them and use two of them to attach a hook to your earring. This way even if the split lines up with the frame of the hook it doesn't slip out, its called redundancy :P
Now you have the hooks! Time to create more Printable earrings everyone!
