Chain fidget with ball joints

Lately I've been playing with modeling different types of joints, this was a quick idea and quick implementation. Originally the model was designed as a non-detachable Print-in-place, but I found out that the joints can be disassembled and connected, they hold the connection very well.
So you can print it as a whole, or one piece at a time and connect - also different colors / they are currently printing /. You can scale it - the pictured gold model is 175%. The green one is the original size.

A good toy for children, and for adults too!

Be careful when small children play with the toy!       Contains small parts!
