Michael K Johnson<p><strong>This design is ready for you to test!</strong></p><p>I printed out keys with six different variations on spring strength, four different sizes of covers, two different heights of swivel bases, and brought them all to my <a href="https://rars.org" rel="nofollow noopener noreferrer" target="_blank">local club</a> monthly show-and-tell. A few others club members have also printed them. I took some feedback, and have now updated the <a href="https://gitlab.com/mcdanlj/Single-Paddle-Key/-/blob/main/README.md?ref_type=heads" rel="nofollow noopener noreferrer" target="_blank">documentation</a> and <a href="https://gitlab.com/mcdanlj/Single-Paddle-Key/-/releases" rel="nofollow noopener noreferrer" target="_blank">released STEP and STL files</a> for multiple configurations.</p><p>The ones I printed were ABS. One club member printed in PLA, and another in PETG, so it looks like this design can work well across multiple types of filament. One club member screwed down what I had meant as a belt swivel mount to a board that you rest your wrist/forearm on and it's a very clever addition! Picture attached.</p><p>I would like lots of detailed feedback! If you are interested in a single-paddle morse key, it doesn't matter whether you want a very light or extremely stiff spring or anything in between, this design can meet your needs. It's not expensive. You may be able to use random hardware lying around the house, especially if you have spare parts for 3d printers, but I also have links in the documentation for various hardware you can use with it.</p><p>Lots of options and possibilities, and if you need help, please don't hesitate to speak up!</p><p><a href="https://social.makerforums.info/tags/AmateurRadio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AmateurRadio</span></a> <a href="https://social.makerforums.info/tags/HamRadio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>HamRadio</span></a> <a href="https://social.makerforums.info/tags/CW" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CW</span></a> <a href="https://social.makerforums.info/tags/MorseCode" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MorseCode</span></a></p>
