One of the finest portable CW paddles you can buy is from Modern Morse. Aaron has made a truly fantastic morse code tool, handmade and designed in the US. Get one, you won't regret it.
Then, consider swapping out the finger pieces with these. Some love the longer stock aluminum finger pads, but I like mine shorter, so I designed some to print up. Turns out they work great.
Print them flat side down so that the part your finger touches faces up. Apply ironing to make a nice smooth surface. I recommend PETG or ASA for temperature resistance.
Have fun printing, and I hope to get you in the log!
