The objective here is to print a line of free standing 3D text on a breakaway bar that holds it in place as printed until installed. Ideally breakaway is the desire, but you need to use a blade to make a clean cut.
I created a video to explain the program Posted in my PrusaPrint library.
www.prusaprinters.org/prints/71776-3d-text-on-a-breakaway-bar
Notes:
Some manual work is required to place the strings to hold the text in place.
Accents and parts of characters that are separate from the base of the character are free floating and will need to be placed separately.
Terms:
The bottom horizontal piece is referred to as the BAR.
The components reaching up to the font are coded as STRING.
If you want to import an object for sizing..
set stl_file_to_import to the file you want (using forward slashes).
set import_sizing_stl to yes
In the code you will need to locate if (import_sizing_stl == "yes"){
change the transpose and rotate to move your object under the text.
I reference a Prusa Slicer feature called ironing. This video talks about it

Attributes You can change:
//Enter text to use in Single Line or First of Double Line
text_first_line = "COMPLAINT BUTTON";
//font size used for first line and SINGLE line
first_line_font_size = 13;
//font to use. See fonts under SCAD HELP and FONT LIST. I usually insert from that list and then copy what I want.
font_name_to_use = "Century Gothic:style=Bold";
//Length of the Bar. Should be longer than font and shorter than your bed. You can always cut it down.
bar_length = 174;
//If you already setup your text connectors and then after you change the bar_length... all your positions will shift by 50% of your length delta in length. This will allow you to adjust it back w/o having to retype the numbers.
offset_adjustment = 0;
//height of the bar... height off the print surface
bar_height = .8;
//bar thickness... the bar thickness top to bottom as the letters go.
bar_thick = 1.0;
//Not all font letters end at the same spot, this will adjust your string closer to so you can touch all the letters
bar_adjust_Closer = .75;
//Height of the font you are printing
font_extrude_thickness = 1.0;
//height of the attach sring... height off the print surface
string_hgt = bar_height;
//The jump is the final part connecting to the font, we want it one or two print layers but leave room for the angel cut. SHould be less than the text extrude height.... probably
string_jump_conn_hgt = string_hgt-.3;
//string thickness
string_thick = .8;
//total length of piece going from bar to font
string_dist_to_font = 1.8;
//this is the lenght of the thin end that will jump to the font
string_jump_length = 1.5;
//FIX IT Arrow Font size .. for my initial project
arrow_font_size = 9.5;
// If you need to import an STL to size your font
import_sizing_stl = "no"; //[yes, no]
// Full path to STL to import
stl_file_to_import = "G:/3d/Complaint_Button_2/Base.stl";
//First Line offsets for connectors. Must start with [ and end with ]
first_line_offsets = [8,11,22,25,32,45, 48.5, 50, 59, 63, 66 , 76, 79 , 80.1 ,85, 92, 98.2, 100, 110, 113, 122, 125, 132.0, 133.5, 139.5, 140.9, 149.5, 153, 161,169];
