This papercraft is a Pip-Boy 3000 Mark IV, the fourth iteration of the Pip-Boy 3000 line and includes a number of design enhancements, based on the Fallout 4 video game, the paper model is created by Nikita Peryshkin. The size of finished model is about 136 (H) x 160 (W) x 131 (D) mm.
The control dials were moved from the left side of the device to the right to improve accessibility, and the biometric lock and glove were replaced by a simple latch, allowing for quick and easy removal. The Mark IV also utilized a revamped display interface with animated images and was capable of playing the latest video games, such as Atomic Command and Red Menace.
The Pip-Boy 3000 Mark IV was distributed to vaults near Boston, including Vault 75, Vault 81, Vault 95, Vault 111, and Vault 114. Vault-Tec staff did not grant Pip-Boys to the residents of Vault 111 due to their placement in cryogenic stasis; the Sole Survivor of the vault was able to claim a Pip-Boy from the corpse of a long-dead Vault-Tec scientist.
