ruler

I created a simple, quick-to-print 15 cm ruler. It's small and compact enough to be carried anywhere, and it has a hole for easy hanging and carrying. The images shown don't have a hole, but the 3MF file is printed with a mounting hole. Sorry, I forgot to include it in the printed model. The model doesn't require AMS, but a pause has been inferred in the Gcode to allow for easy color changes.
