Artistic Cube - Khối lập phương nghệ thuật

A cube I made playing around in Blender while listening to an audio book. Designed so each face is printed diagonally and snaps into a central frame/mount. Brims or mouse ears would be a good idea. Enabling supports for the frame is recommended, though the areas requiring support are minimal. None of the functional areas require support. Everything is positioned in the STL in the recommended print orientation.
