Search for DeDRM plugin for calibre. There's several ways to do it. If you have a physical kindle, you can download the books from your amazon account, and plug the serial number of your kindle into DeDRM. If you have the Kindle for PC or Mac app, DeDRM can pick up the relevent keys. I recommend getting the books in the AWZ3 format rather than KFX.
I couldn't make the desktop application ripping mechanic work. Apparently you need to download an ancient version which still uses AWZ3 since KFX wasn't support. I got lucky since I had an old gen one kindle on my account so I was able to download the files from my account portal but I think I would've been out of luck otherwise.
Ah yes,I have kindle keyboard (it won't die!) so maybe one will have problems with the newer versions? After installing Calibre plugins, simply double clicking to download books to my local library automatically strips the DRM.
