Very nice!

Not free, but the "Technic", "Simplex" and "ISOCP" fonts included with AutoCAD are also of this aesthetic, if people want an exhaustive list of candidates.

For single-stroke (AKA "routed") fonts of various aesthetics, look up SHX font files. I'm not sure what the license status is, but they're easy to find online. I use them for laser cutting.

I’ve tried to find “the autocad font” so many times before. Thank you!
