My own version of https://www.printables.com/model/334530-nasa-neon-with-el-wire that I've remade fully from scratch.
It's a little tight for EL wire and was designed for LED n00ds (though I've yet to find any long enough for the continuous version.
Continuous (single wire, only two holes) and non-continuous (separated letter segments, multiple holes) version provided
The gcode contains both continuous and non-continuous together.
The author marked this model as their own original creation.
