The only spot available did not have any space behind the panel to allow mounting the LCD from behind. I used the small LCD backpack Nano carrier board designed by wiseguy, and fitted a ribbon cable from that PCB to the LCD module. This allowed the LCD to mount flat on the front panel, with 4 tiny spacers to just clear the LCD metal work on the back of the LCD module. A small slot behind the LCD allows a ribbon cable to lay flat with no signs of any connections, it plugs into the small Nano carrier board mounted 100mm away. The only problem I encountered was - the LCD displayed garbage - some unnamed dumb arse forgot that he had written the LCD code for a quick and dirty veroboard Nano carrier to mount the test LCD on a few months back. After wasting an hour, I'm getting old, the penny finally dropped, a quick change to the code for pin assignments and it worked perfectly. I need to make a small black cover with an LCD display cutout, it should look better  then. .
