A base that securely mounts to the sBITX HF transceiver case that you can mount your CW key or paddle to for portable operation. Also has a hanger for the mic.

Designed in OpenSCAD so can be modified. Uses original case screws. Screw holes are countersunk so screws do not protrude. 

I use it with my hand open and draped over the top. I suggest that you mount the pad and just move the paddle around until it feels comfortable, then adhere velcro/duo-lock/… it down.

I printed mine in grey PETG.
