Yet Another Whiteboard Marker Holder

Another wall mountable whiteboard marker holder. This one is not parametric, does not have an eraser holder and does not fold out. It's boring. I made it before I thought to look here for more awesome ones. It does hold the 8 of the standard Expo Whiteboard Markers though. Designed to be printed at 0.2mm Y, and 0.4 XY. You get 4 base layers, and 3 line walls.
