This papercraft is a Spawning Pool, the first Zerg tech building, a pit of primordial ooze in which is contained the genetic makeup of the Zergling, based on the military science fiction real-time strategy video game StarCraft, the paper model was created by stange1337.
Building the Spawning pool also unlocks the Lair, Roach Warren, Baneling Nest, Spine Crawler, and the Queen.
The Spawning Pool is a high priority target for the opponent, so it is advised to place it somewhere hard to reach. For most of the first year of the game, conventional wisdom dictated that the safest spot of a base was behind the mineral line. However, the increasing prevalence of drop play has suggested that the middle of the Zerg base may be safer. However, placing the Pool strategically near the mineral line can prevent enemy scouts and harassment from easily maneuvering around your workers.
Two upgrades are available at the Spawning Pool, Adrenal Glands, and Metabolic Boost. When an upgrade is researching at the pool, the structure pulses and the surface of the pool is seen to froth.
