Holds dry erase markers. Just glue it to the border of your dry-erase board.
0.1: I'm abroad right now, so let me know and I'll tweak the marker diameter as needed - It might be a little loose right now.
0.2: Changed the inner diameter to 17.25mm, to fit a 17mm marker. Made the opening of the hole larger.
