This is a tool to make your own rings with wire. With the Fusion 3D-File, the ring size can be set by yourself.The attachments have a thread to be able to print different attachments so that they can be changed. The hexagon on the top is there to make it easier to screw the attachments into the thread for the handle.

You need support on the thread for the attachment.

I will upload more ring sizes as soon as possible.

Have fun making your own rings.
