Ruler 20 cm

This is a 20 cm ruler, perfect for school. It is a quick and easy print. I used my CFS to change filaments midway to make it easier to see the numbers. You don't need to do that. And if you don't have a CFS but still want the same look, fear not. You can easily replicate this look by making the slicer pause the printer at a certain layer, then change filaments, and resume printing. This ruler can be used to measure, and draw straight lines.
