I don't know where I had my mind. Offset would not preclude the difference to get an outline. Sorry about that.

If your intention is to have an outline of the symbol \ue625 it may be simpler to do an offset() of it instead of the difference().

Sorry about that. > Otoh, offset may help clean up self-intersections. This seems to do the trick: difference() { offset(-0.1) text(text = "\ue625”, size = size, halign = "center”, valign = "center”, font="mana:style=Regular"); offset(-1) text(text = "\ue625”, size = size, halign = "center”, valign = "center”, font="mana:style=Regular"); } In this case, you could also wrap the text in a module as it’s the exact same symbol instantiated twice. -Marius

Another trick: You can "use <mana.ttf>” directly in the scad file. This allows you to distribute the ttf file with your OpenSCAD file and you won’t have to install the font system-wide. -Marius
