Now might be the time to refresh people’s memories: you can export SVGs from openstreetmap.
It’s not as simple as this little widget in the OP by any stretch, but it does allow you to do some really impressive mapping projects.
Go to: https://www.openstreetmap.org/
search where you want to map…
Then (while in the standard view mode) click “share” on the right side. You can export it as SVG. Then it’s just a matter [in Inkscape, anyway] of using “select same…” to isolate what parts of the map you want.
I was able to whip this up in just a couple minutes.
Those are all paths, I could score it or convert it to outlines and preserve the thicknesses with a proper engrave.
Power move: color code the various thicknesses and score everything but at varying degrees of incorrect focus to get thicker lines. Should be faster than engraving by quite a bit while still preserving some of the line thickness data.
