I found this case at Harbor Freight [see above]. It adds weatherproofing and I put in a 3D printed key I make and cables and a pen and notepad for logging and copying CW.

Here’s a link to this case at Harbor Freight; it seems to be their equivalent to the Pelican 1060 which is an ideal size for many compact QRP radios.
Thanks for the tip, Joe!
