Morse paddles

thingiverse

This design is for two different versions of 3D-printed iambic paddles for sending Morse code. The design is simple, but provides precise movement with adjustable force and travel. Design features include printed rocker hinges, force adjustment by a sliding spring, travel adjustment using a modified screw, ergonomic grip and general simplicity and precision. The design is compact and well suited for portable use. The design can be tuned or modified by changing the OpenSCAD code, for example to change the paddle shape to your taste (but consider trying the somewhat unusual default shape first). Assembly instructions are given in a separate document. The version 2 of the paddles is a bit sleeker, and also more robust against pushing the arms out or place, thanks to a base that extends under the full length of the arms. The space inside is a bit more tight, and the central screw has to be shorter. Otherwise the design is essentially the same as the first version. Both versions work fine. This design lives on GitHub here: https://github.com/tskauli/MorsePaddles. Version 2 is used in the Compact QCX enclosure (https://github.com/tskauli/QCX_enclosure_LA4ZCA).
