This is basically an extension of the openSCAD new text example.
The Halloween “Danger” example was done with:
Phantom Fingers font found at:
https://www.1001fonts.com/phantom-fingers-font.html
Note that the Fill function requires the development release of OpenSCAD
https://openscad.org/downloads.html#snapshots
I printed this with a layer change, the background as black and the letters with Glow in the Dark.
The problem solving logo (which I'll post if people want) was made by editing the openSCAD file, but single words can be done with customizer.
The author marked this model as their own original creation.
