Self adhesive print

This can easily ordered by online photo print services.  Probably such a label will start to loosen by the edges.  It might get dirty.  It would still require for the housing to be milled.

PCB Front panel

Front panel can be drilled, filed until the PCB fits.  It doesn't have to be a perfect job.  It will be covered anyway by the PCB front panel.  The labeling can be done in silkscreen.  Silkscreen is a high quality print, it will not wear or tear off.

First job, convert the dwg design files to dxf using cloudconvert.  Then clean up and scale the front panel in Librecad.  Then it can be imported in EasyEDA.

The final front panel will be ordered in yellow soldermask.  It will be ordered after Chinese New Year because now they charge me $43 if I don't want green soldermask.
