BK-50 Swallow Bug Key Paddle

A replacement Paddle for the BK-50 Swallow Bug Morse Key.
Please read info below!!
The original Swallow Bug paddle was curved to fit the thumb. As I am new to 3D printing and CAD design, I designed the paddle to be printed flat. Therefore to achieve the curve, it is best to print in PLA and then heat the paddle up in some hot water. once it is malleable, you can then form the curve with your thumb - PLEASE WEAR GLOVES when doing this!!
I made the forward screw fitting into a slot, to allow for any variation in key fittings.
If, like me, you don't have the original paddle to use as a guide for forming the curve, there are plenty of photos on the Web to go by.
Please see my other design for the matching knob.
