Here is a morse key I made. It has holes in it for feeding 22# wire through. I used maget wire 22# for this and works great. Also uses a gumband for the spring action. Must print the KEY with support.

I used hot glue to hold it down to my table. You may be able to use tape or bubble sided tape.

I added a .05mm offset KEYER so there will be less travel for the keyer for faster CW sending.

1.) Print the parts.
2.) Put the Key on the base.
3.) Feed the 2 Wires through the holes.
4.) Add the gumband.
5.) feed the base wire from one side RIGHT to LEFT and hot glue it down on the left side.
6.) bend down the KEY wire on the KEY. Left 3mm of wire after bending.
7.) strip the wire where it makes contact with a razer blade.
8.) Hot glue the KEY wire at the back.
9.) Connect to Radio with a 3.5mm jack and have fun.
