This is my mimic board I made for my H0 layout.
It was made using a layout planning software - probably Hornby - and then altered in "paint" to add text and "Dots" for the drill holes.
The printout was then laminated , stuck to a plywood panel and drilled at the dots for LED point position indicators and push-buttons for the point motors. LEDs are just pushed through from the back into tight holes.
The panel is hinged at the bottom for wiring access.
Before anyone asks the box at top right is a remote point motor controller with IR handset ( left centre) which means I can control points and routes from anywhere in the room or by the panel push-buttons.
Hope this gives some ideas. Regards, Colin.
