morse paddles

this is a work in progress make at your own risk. I made this in one night so I could send my niece home with a morse key. It works but It isn't perfect.
UPDATE: there's a newer version of this here: https://www.thingiverse.com/thing:5403763

this was printed using PETG I'm sure other stuff would work too.

the center conductor is made from 1/4 in copper pipe soldered to a ring terminal

The 3.5 jack is a trs screw terminal jack https://www.amazon.com/3-5mm-Stereo-Female-terminal-connector/dp/B077XPSKQD this is just what I had lying around

fasteners are 3mm

PS if yo find this useful feel free to buy me a cup of joe
