The completed kit.









Here I have selected a suitably sized box and made a cutout with my router for the display.






Next a piece of plastic from a CD cover is cut out to be used as a bezel.
The CD cover plastic is easily scratched and this was my second attempt to get it right.






The bezel is then glued in place.






The remaining holes are drilled







...and everything is installed.
Finished kits need not look like they have been cobbled together from junk box parts.  :-)
