Master System Control stick replacement handle

Disclaimer: This was done to a broken controller, if you butcher a controller that's in great shape to install this, that's on you. Recently scored a batch of Master System control sticks from a convention and one had a broken handle. Decided to make a ball top for it and after you remove the handle cleanly which has to be cut off to be removed, after removing the screw under the top. This has a very snug fit and shouldn't need any adhesive unless you're a rage gamer and you like to throw controllers haha. Hopefully, this will help someone with a broken controller.
