Inspired by the modular paddle on the Elecraft KX3, I designed this to directly attached to the (tr)usdx. Combine this with the battery pack from Manuel and you get a very compact CW package. I printed this using PLA. To assemble the wiring I suggest to solder the wires to the stereo plug prior to press fitting the plug into the key to keep from melting the plug hole in the key base.
