Mushroom Bento Box: Tray Inserts for parts and materials

I thought the idea of this mushroom twist box is really neat, however, I wanted some trays to put inside the mushroom box to store little odds and ends.  

These trays should fit 3x , as shown, in each mushroom, with a built in divider and little handle to pull them out.  First picture highlights the tray size inside the mushroom body, second pic shows 3 colors of trays stacked in the same volume.

I hope this helps people store things inside their mushroom twist boxes!

Since these are simple trays, printing in just about any filament ought to work.  They're designed to be 2 walls thick with a single wall thickness setting of 0.42 mm.

STEP file included, because only STLs is a pain :).
