Kwik Stick holder (Tempura paint sticks)

My kids have a 24 pack of tempura paint sticks. The box they come in is pretty awful for repeated use. What good is a 3D printer if you can't print a box?

These have enough room for 24 (tempura.stl) or 12 (tempura_3x4) markers to be aligned in a zig zag. There is enough room to get the middle ones easily.

These are an example of the markers:
