Here is the Laserkraftwerk Laser cutter/laser cannon from the game Wolfenstein. Its comes in 69 individual parts that fit together using dowels to create final weapon.
It was created from reference images of the weapon taken from in game at certain stages that allowed you to see both sides of the weapon and additional concept art I was able to find as I went along. The right hand side was particularly difficult as there is only one real occasion in the game where you see it so it meant taking the best images I could at the time to recreate it. To ensure it was as close to the in-game version as possible I ended up manually recreating the warning and safety stickers on Inkscape, a free vector drawing portable app, which I then printed, lacquered and applied to the finished prop. These stickers are included as a PDF to print as part of the files. As this is a bit of a beast, I have create several isometric and exploded isometric views and layout drawings to show the build and how everything fits together due to its complexity but I've made the build as easy as possible. I have also included a standard 3 view orthographic drawing for anybody wanting to create theres from scratch.
The model itself has several moving parts, the front charging rail can be lifted into the charging position like in game and the front handle can be swiveled 90 degrees to give a different grip layout. The side panel of the front chamber is also removable to show the inner parts and the central beam focusing barrel rotates to show the inner barrel chamber. The receiver piston linkage also can be cycled.
