This is a model that was originally by Bethesda Studios Fallout Dev Team. I found this model in MyMIniFactory.com
All credits go to Bethesda. I found this model when Jeff Lagant posted this. I am incredibly disappointed by the lack of Fallout props in Thingiverse so I am trying to gather a load of models from other websites to build up a fallout community in thingiverse. When I typed up pipe gun in the search bar (hoping for a model like this) I was disappointed by the lack of models. In response to this I went on the MyMiniFactory.com and typed it in there. This is the best model i could find for the Pipe Pistol design. I recommend watching a video on youtube on how to paint this and make it look good as well as putting tape around the handle(unlike the pictures) to make it game realistic. I hope you guys love it.
