Pen Storage Box/Trays

Pen trays, designed to fit in an old earbud box of mine, but self-sufficient regardless.

The bottom tray is one piece, while the top is half of the bottom one. Two top trays stack on one bottom tray, and top trays can stack on each other. Top tray holds 7 pens; bottom holds 14.

PRINT INSTRUCTIONS: The bottom tray doesn't need supports, and the top tray needs supports from print surface. Print them horizontally, like how you would use them; ignore the orientation in the model files.
