I have released version 0.5 Beta of my #HamRadio single-paddle #Morse key.

I added optional stabilizer bars for which I recommend 3mm stainless rod, to counteract torque from the center of pressure on the grip being above the spring. (That twisting has been the main thing about the key that has caused me to inadvertently send wrong code as the head of the center contact screw bounces off the edge of the dit or dah screw.)

I made the lever more compact, which required adjusting the range of default spring force from the integrated springs. I also removed the heaviest weight that no one liked.

The README has instructions, information on options for required hardware, and complete documentation for all the parameters that drive this single key system.

This is a release candidate for version 1.0. If you like CW / Morse code and 3D printing, and either like single-paddle keys or would like to try one, please give this a shot and tell me how you like it! It's been successfully tested with PLA, PETG, and ABS, so it should work with most common filaments. Just don't leave it in a hot car if you print with typical PLA!

Feel free to ask questions in a 🧵 thread here!

Here is my current morse code key with all its parts prior to assembly, as well as after assembly. In addition to these parts, you need:

• 3D printer to print the key
• Wire stripper
• Soldering iron
• Wrench or pliers for the 1/8" fixing nut
• Spiral-flute M3 tap
• Appropriate cutter and files or sander to make optional stabilizing rod (don't use your wire cutters for stainless steel unless you want to destroy them!)

I have sources for all the parts except the (commodity) stranded wire linked in the README.

One of the main things in the way of publishing this as version 1.0 is taking all the pictures I just took (far more than these) and assembling them into an assembly guide.
