This is the same item as hippiegunnut's http://www.thingiverse.com/thing:12307, tweaked very slightly with an optional lid added.
-- UPDATE 4/13/2013 --
I added a second type of box: now you can use a sliding lid. Prints nicely, with a very steep angle in the lip so no overhang problems. I'm using these as chess boxes, card deck boxes, screw sorters, etc.
Still fully parametric, of course.

Okay, finding a lot of uses for this recently. :)
I added a parameter to include a coin slot in the lid. Now it's a divided piggy bank too! (My 8-year-old son uses it to handle savings, etc. separately.)
Print. Put lid on box. Or slide lid into box, depending on what you printed.
