Letter vary in height and width from about 65mm to 80mm and are 20mm thick. They can of course be scaled to the required size. For a nicer front finish, try flipping the letters face down if you have a smooth or textured build plate.
Tips:
Try different infills with the top or both top and bottom layer counts set to zero to create different styles of letters. Below are some examples:
No top and bottom layers, 10% octagram spiral infill
No top and bottom layers, 10% honeycomb infill:
No top layers, 0% infill:
