8 Whiteboard Marker and Brush Holder with dust openings

I remixed this to add dust holes in each marker hole as well as a square hole for the brush holding area. I don't want dust or bits of brush collecting and gunking up the bottom of the holder, so this will keep it cleaner plus, you can push your finger through the bottom to get the brush out.

I also reduced the height of this slightly from the original as I didn't need it that high. It reduced my overall print time from ~7hrs to ~5hrs.
