Had this aluminum plate laser cut a few months back and hand-wired it with Box Navies and a RPi Pico, and oiled oak for the sides. I missed my numpad, though, so I used my own laser cutter and made an external one from Masonite and textured spraypaint.

I’m not sure where it will live long term, but “southpaw” numpads are definitely a thing. They allow for mousing while doing data entry, and they mitigate one of the reasons some people do without numpads by allowing the shoulders to stay more neutral when the mouse is close to the right edge of the keyboard.
