Don't be on fire

Simple remix to change text.

Rule 0 of many Hackspaces is "Don't be on fire!". There was already a rule 1 and (in retrospect) this one is more important.

DXF added for those who like burny lasers and/or ouchy CNC cutters.

I've now also added separate stls for multi-part prints and the OpenSCAD code that makes these changes to the original. Note the centres of the letters print with the frame and you'll need to save these carefully to drop in after the letters are glued in place. Things deliberately print face down as this is much better if printing on glass. Flip things over if you prefer.
