IKEA_TROFAST SMALL_box insert

TROFAST inserts for the small boxes (20x30x10cm)

Look at IKEA_TROFAST SMALL_box insert (2 levels) if you prefer lower boxes instead.

Optionally, print also lock. Once as it is and another one mirrored.
Stick locks into grooves in the bottom. Small boxes will be fixed in corner positions but you can still take them out.
