Small Dry Erase Marker Holder

A holder for small dry-erase markers and a small eraser. Can be set on a desk or mounted to a wall/whiteboard with command strips, double-stick tape, or stick on magnets. Holds 11 markers (I know it's an odd number, it how many we have). The back wall is tilted out slightly so that when affixed to a wall or whiteboard there's more space to grab the rear markers. The rear markers sit 10mm higher than the front for easier access as well.

Critical dimensions (as designed, allow some tolerance for your printer):
Hole Diameter: 13mm (loose fit on the markers we have)
Hole Depth: ~80mm front row ~75mm back row (actual depth varies across slope)
Eraser holder: 22mm deep x 86mm wide x 25mm tall

If you're printing the one without the eraser holder, I suggest aligning the long axis with your bed axis so it's less likely to fall off from bed movement. The one with the holder has plenty of contact area and shouldn't matter which orientation you use.

For infill I printed one without infill and one with 10% infill. The 0 infill print has a very flexible back. The 10% infill print has a very sturdy back and also printed much faster since it didn't have to bridge the entire cross-section for the bottoms of the rear holes.
