I created this cube to use it as a background item in sci-fi related scenes but it is fully functional and can be used to store items. You can open the top of the box to store your items. (Box's lid opens via shape keys.Shape keys are only included in .blend,.fbx and .dae file formats.). It has charming red lights which can be changed into any other color easily. If you are a Blender user, box's color will automaticly change into green from red once you open it by using the shape key.Check the preview video to see it in action.
There is only one texture and it is a normal texture used in both the black and metal materials.The texture is not included in obj and fbx files so you have to apply it but I think model looks cool even without that texture so it is up to you wheter you apply the texture or not.
I did some changes to make the model available in other file formats. It looks just the same but has extra verticies to prevent glitches that don't occur in Blender.Stl file format is added to give you another option while importing. The model is not ready to be 3D printed.
