This is a (toilet)sign with the Arduino UNO. Arduino is a microcontroller i use to program little stuff like leds and push-buttons.
I have printed this model in multi-color, with a single extruder. It is also possible to print this model with one color.

Ultimaker & Octofiber PLA
white & black
I have printed this model with Ultimaker white PLA and Octofiber black PLA. I used 0.2mm layer height and, 18% infill. I used a 0.4mm nozzle with my extruder at 210 degrees Celcius. I used a heated bed. To avoid the curling up at the bottom i used a brim. I paused the print at the point when the text began, changed filament, and resumed the print.
