A simple box to store small things.
The inner dimensions can be adjusted and the latch on top makes sure that it doesn't open when it shouldn't.

UPDATE: now with the option to add more latches

I printed this thing on an Ultimaker 2 with a layer height of 0.1mm.
The hinges for the lids are designed to be printed in place.
The inner Dimensions can be adjusted via the height, width and length variables.
If the box is very wide you might want to add more latches by using the "latches" variable. But remember that the latches are about 15mm wide.

The display options are there to show the box in different configurations. To use them set the "print" variable to "0". Don't forget to change it back before printing.
The variables "close" and "lock" are there to show the box in the opened and closed positions.

To assemble it just clip the two parts of the latch in place and enjoy your print ;)
