40mm box with lid

This is a simple box. It is 40 mm wide and 30 mm tall. with the lid it is a 40mm square.
The lid is 40mm wide and 10mm tall to complete the cube.

The walls are thin enough to allow light through if you put an LED inside. The picture of the lit up cubes is a revision of this cube with places for a switch and a button controlling an RGB inside. Im going to post the schem and assembly guide ASAP. I just have not had the chance.
