KM4CFT Straight Key
I needed a 3D printed key for a QRP vacuum tube (valve) transmitter that didn't expose me to B+ voltage. This fits the bill with one modification. The one screw in the arm was painted after installation to insulate it. Generally works well. Key arm is not as stiff as I would like, tho. A 'C' or 'I' beam type print might help that.
