Expo Marker Clip (click the little "full screen" button to see the full sized images) This is a magnetable clip for holding Expo markers. Print it out, slap some sugru or superglue in the hole in the back along with a maget, clip your markers in, and BAM! You've got yourself a Magnetable Expo Marker Clip. I'm putting up whiteboards on my walls, and I glued a few magnets to the backs of them. This way, there are no pesky magnets sticking out of my wall, and I can stick Expo Marker Clips to my wall really slick-ly.This design may need some fiddling before making it the right size for your printer (I printed it on a Printrbot Jr. (v2)). The magnet I used was a Magcraft 1/2 by 1/8 in rare earth disc magnet (http://tinyurl.com/nh5jxow)
