Yes. I'm looking for a Linux program that can turn SVG into signs like that (STL). Because doing it manually is a lot of work.

(Maybe it is easy to do in OpenSCAD?)

Check out Kiri:Moto (open source tool which can convert SVG into 3D shapes, and export to G-code appropriate for 3D printers, CNC routers)

Thanks, but Freecad can also do it. The point is that it is a lot of work to import, extrude, etc. I would prefer a commandline tool that takes the name of an SVG (or DXF) file, and outputs an STL file that I can directly send to my printer (slicer, actually).

Hueforge has an AppImage. I'm on mac so I don't know how well that runs, but it's what you're looking for.
