This star trek papercraft is the Borg Tactical Cube Space Ship. This paper model is designed by Sirius Replicas. There is a 2-1/2" version and an 8" version. The Tactical Cube is one of the most powerful Borg ships. They are heavily armed capital ships with many capabilities from tractor beams, subsystem targeting and sensor jamming. They usually travel alone, or accompanied by other Borg elements as well. They are also larger than most Borg Cubes.
The Borg Class 4 tactical vessel was a type of heavily-armed Borg cube utilized by the Borg Collective. The tactical cube differed from the standard Borg cube in several ways, the most notable being the extensive hull armor that covered a large portion of the exterior hull of the ship. The interior was also slightly altered from what is known of Borg "architecture". The vessel's central plexus was protected by multi-regenerative security fields.
Only one such vessel was observed by Starfleet – by USS Voyager in 2376. The tactical cube was caused to self-destruct by the Borg Queen during a brief civil war within the Collective.
