About This File
This file is a very very small model of a cube (0.001m).
It is intended to be used to attach menu icons to assets, as explained in my How to add custom Menu Icons to (Almost) any Asset - The Hard Way Steam Guide.
It was given to me by an anonymous user, who authorized me to upload it here for all who need one to use.
It's completely invisible in-game, so I can't really add a real screen-shot. Sorry.
For more information check the guide.
