This is a collection of all the letters to make anybody's name. This was done in Inventor so if you have that you can create the name as an assembly first. Otherwise, load the letters that you need and adjust the coordinates so they overlap.
For instance in Repetier-Host, I would load the letters. Set the Y coordinates to be the same, then adjust the X-coordinates so they overlap a little. Then when you go to slice it and it tells you things overlap, quit or no, you say no. It will sclice it just fine.
