Morse Paddle Key MKII

This is a small CW Paddle Key
It is less than 3.5in long overall.
It has provisions for 4 flat head screws to attach it to a surface.
It is a revision of my previous design: https://www.thingiverse.com/thing:5402839
UPDATE: I added some paddles with bigger pads as an option.

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

the center conductor is made from a 12-13mm long piece 1/4 in copper pipe soldered to a ring terminal
It requires
(2) M2x5 machine screws
(3) M3x20 machine screws
(2) M3x6 or M3x8 socket head cap screws
(2) M3 nuts
(2) M3x5 machine screws
(3) ring terminals that fit over the M3 screws
(1)3.5mm TRS jack*
(1)0.8x8x20mm coil spring**

*This uses a 3.5mm TRS jack like the ones here.
