Penny Press head

This is a head for my Watch Back Press set (I have one from Ruihua).

Since I was making a batch of tri-spinners that take pennies, I needed a reliable way to press them into position before gluing so I designed this to screw into the top of my press and use a standard flat end from the press itself to get the pennies in. The hole down the middle was just right to self-tap into the screw on the press.

The head is slightly smaller than the penny, but will provide consistent pressure.
