I have a piece of audio gear (drum machine) I'm modding for a client; it didn't originally have an LED display but it will, soon. What's the least aesthetically offensive but reasonably durable way to mount a ~1.5 inch by 1 inch through-hole 2-digit 7 segment display with daughterboard PCB to the front panel of a desktop enclosure, and route the segment lines to the device's internal control electronics?
Drilling a small hole or two in the front panel or sides for routing purposes is OK, but say cutting open the enclosure with a nibbling tool to make an opening wide enough such that the display can be mounted from underneath is not.
