3D Printed 45 RPM Record (Not Playable)

This is something that was sitting on my TinkerCad page for over 4 years and I had forgotten all about it, but its a 45 rpm record that as far as I know is not playable but it may be. I am printing it right now so who knows.

This design had to have come from somewhere its not mine , it may have been modified from somewhere else but I am posting it because its interesting and its not mine, it may have been even from here , who knows.

If someone can let me know who designed this , I can give the proper credit where due.
