Smudge Free Art Ruler

thingiverse

Got sick of the smudges left by regular rulers when I use micron pens to draw straight edges. I never liked the metal rulers with the cork at the bottom because it was so hard to see the line and align your pen correctly, and the edge was much too low. The edge on my ruler is much higher so you should be able to use sharpies without the delicate inked tip marking up your ruler. I printed it at .12 with regular PLA and it works fine. I tried to save some material here and there as well. Art school isn't cheap! Enjoy, and let me know what you think!
