Simple to print and build pocket sized Morse Paddle. This paddle is based on OM2JU design. Connection to keyer or radio is made by 3.5mm stereo Jack-Jack cable.
The parts are easy to get in your junk box or local store or ebay, aliexpress.
Use super glue to fasten jack socket.
Wiring is done by thin wires.
I will add picture of wiring soon...
Use 100% infill for paddles
For base plate use solid infill setting for small areas in slic3r.
There are 3 types of cover. You can use color print https://www.prusaprinters.org/color-print/ to have nice sign on the top of the cover. If you don't like color print use nosign version of STL.
