The 100 set of Crayola markers comes in a box with a flip lid, but the markers are really crammed in there. I designed this holder to make it easier to find and select the color you want. The holes make the marker arrangement almost as dense as the box but the different levels make it easier to add and remove markers to a consistent location.

On my FDM printer (MonoPrice Mini Select), the cooling of the model makes the bottom of the stand a bit convex, allowing the container to spin on the tabletop. That was NOT part of the design but I'll take it as a serendipitous bonus. :-)

On the MonoPrice Mini Select with 0.2mm layer height and 20% infill, this print takes about 27 hours.

This model holds 50 markers, because the 100 marker version wouldn't fit on my printer. You can print two copies of this 50-marker version and glue them together to get one 100-marker container.
