Whiteboard Marker Pen Edge Holder

thingiverse

I used a weak magnet on my whiteboard and heavy pens just weren't sticking. The solution was simple - I either needed to create a holder for a stronger magnet or get creative and let the pen hold onto the edge of the board. And it works like a charm! The marker fits perfectly in place with friction so you can swap out your markers at any moment. I also came up with a variation featuring a belt clip: http://www.thingiverse.com/thing:1323181
