Rotating Sharpie marker carousel. This is designed specifically for the 24 Count Ultra-Fine Point and 24 Count Fine Point markers so that each ultra-fine marker is held directly behind its fine point version. The top tier of holes are slightly smaller and they will not fit the larger of the two markers, so the ultra-fine go on the top and the fine go on the bottom. It uses the 12x3.5mm bearing from Maker World for rotation.

There is also a sizable well in the middle for scissors/pens/pencils/ect.

I also added some rubber feet/bumpers (the kind on cabinet doors) to the bottom so it sits nicely on the desk.
