This will make a 3D model that is like a "cube" made with two letters. From one point of view, let's say the front view, one letter will be seen. From the right view another letter will be seen. I did it for the first time using Blender, but wanted to make a customizable model, as I started to print it as a gift for people who came to my house and got interested by the 3D printer.

One may notice that the pictures model is different from the rendered one. After printing I've made some code adjustments to improve the letter width correctness. It can still generate small letters cut, but I guess it is good enough.

Another improvement has been the optional base generation, as many letters won't stay standed up.

Code obtained at https://www.thingiverse.com/thing:3004457 to measure the letters size.

The "Customizer" only works with one big file, so I've created an additional file for it called initials_cube-customizer.scad. If you download files for rendering locally, use the other 3 *.scad files and render initials_cube.scad changing first variables on the file.

Until the last time I've tried, the customizer was not working with this model.
