Or Librecad…

Wont get into the politics, but this is one of those open office vs libreoffice things where a commercial firm supported an open source product but decided to monetise it a bit aggressively in the opinion of some of the community developers, so it was forked…

That was a while ago, one assumes they’ve sorted their differences out by now. :-)

(I use librecad, because it’s in the debian repo, but used to be a keen qcad user…)

Once printed, the paper can be laminated onto the actual front plate material by painting it with epoxy resin or a clear varnish. You can then still drill and cut your openings (carefully, so that the rest of the front plate printing isn't damaged). Alternatively, I have also made front panels from PCB material in the past - it has reasonable mechanical properties for that purpose, and often there is some of it floating around anyway. Or, if you are getting a whole PCB panel made anyway, and the actual electronic PCB is small, just use the rest of the PCB panel for the front panel.

This technique can also provide some RF shielding.
