Signs for miniature railways. Make your own in the customizer. If you don't want holes in the corners, putting zero in the hole size box will fill them in.
Putting a small number in the countersink box will produce a countersink on all four corner holes.
F space is the letter spacing. 1.1 works well for printing.
Using some different fonts may produce odd vertical line spacing. To tweak this, you need to alter the translate statements in the customiser. If there is too much problem, I will try and put some extra variables in!

For those that don't know, the fonts used by customizer include Google fonts https://fonts.google.com/ Typing one of these in will alter your typeface.
Update - I made a mistake in the code that only shows up with a large letter depth. Code now fixed!
