    description = """
This box is designed as a housing for electronic projects. It has hatches that can be re-opened with simple tools. It intentionally cannot be opened with bare hands - if build with thin enough material. The hatches are at the x sides.

#### Assembly instructions
The main body is easy to assemble by starting with the floor and then adding the four walls and the top piece.

For the removable walls you need to add the lips and latches. The U-shaped clamps holding the latches in place need to be clued in place without also gluing the latches themselves. Make sure the springs on the latches point inwards and the angled ends point to the side walls as shown here (showing a different box type):

#### Re-Opening

The latches lock in place when closed. To open them they need to be pressed in and can then be moved aside.
