The regular Gravity Gun is already the most useful weapon in video game history make it so that it can suddenly work on organics, and you got something even mightier than the BFG from DOOM. In a weapon like the Gravity Gun, which comes from a game that came out almost 10 years, the model quality is pathetically low. Last but not least is a variant of the Gravity Gun from Half-Life 2, which turns its wielder into a god. Secondly, especially with older games, a lot of weapon and items models are incredibly low poly and have a great number of their details in their texture. Especially in view models, which are the models you see in your HUD when holding a weapon, any side of the gun that isn’t viewable from the camera gets removed to save rendering time. Unlike in Half-Life 2, where Gordon's first weapon is the crowbar, Gordon first acquires the Gravity Gun, which plays a crucial role in the game by allowing the player to use physics to manipulate objects at a distance in both combat and puzzle-solving scenarios. Most of these models are built in such a way that there are many intersecting solids–that is, two objects sitting inside one another without any way to connect – or with many missing “faces”. Props from video games make the first steps easy, since in most cases you can easily extract a game model into a workable format.

Coming from a 3D design background, my primary prototype building methods utilize laser cutting and 3D printed parts.

You can see the size of the weapon here, and I used this image to help determine the scale used when building everything.
