Looks like it gets broken when the letters are added
Take the STL, and throw it into netfabb cloud repair. It’ll fix it and spit out a usable file.
@ThantiK the point is that openscad refuses to generate the stl file
so, the problem is with the letters, i will try to change the font and see what happens.
i ended usings write.scad instead of Candice.scad. That did the trick
