Cut out a pocket

Are making a sign house nr. 6
how to cut out a pocket inside the " 6 " that is 12 mm
the 12 mm need to be a " 6 " inside the 6.
are putting a silicone led tube in the cut out.

This is going to be best achieved in Adobe Illustrator or a similar vector graphics package and imported as an SVG. The issue with trying to do this with fonts is that letters don’t usually have uniform widths throughout the shape.

ill try to use a other program to get it. thanks
