Going to shamelessly plug the open-source board I designed a few years ago, the Boston. The files are on Github here.
(thanks to RNDKBD for the image)
I wanted a board narrower than a full-size, with a full 2u zero and a traditional 2x3 navblock in a 7-row layout similar to the old Thinkpad keyboards. I added the extra keys and knob just to even the board out and make it a battleship.
RNDKBD still has the 3D-printed version, and previously sold the CNC aluminum version. You can also have it manufactured from the files on Github.
