Inspired by the tile signs in the New York Subway, this model allows you to make your own sign
using your own text. Two different fonts are provided. One is a 3x5 block composed only of whole
"tiles" and the other included triangular half-tiles for an easier to read font.

This print requires a multi-filament (3-color) printer. I am using the Bambu X1-Carbon with the integrated
AMS to switch between colors.

The OpenScad file needs to be rendered 3 times: 1 each for black, white, and blue filaments. These can
be opened in Bambu Studio and combined for resizing and orienting on the print bed. Each "part" will then
have to be assigned to one of the colored spools in your printer.

You can use the Customizer to select the font to use, as well as edit a message of up to 4 lines of text.

Other options let you modify the size of the tiles, inter-tile spacing, etc. The default is a 10 mm square tile
which allows for short messages to fit on a standard print-bed.

This model may be updated in the future - see these github links:
