This model is based on the pistol added to the game Space Engineers with the Field Engineer update. It comes as three pieces that can be adhered with glue, epoxy resin, etc., or it can be printed all at once. There is no function, it is just a static prop.
This contains an .STL for the whole pistol, and two sets of it broken into three parts for easier painting and modification. The first group uses the unnumbered grip and barrel, and "SEPWF_Frame_2" This is the only one that I've printed, and there are some tolerance issues, though the set fits together well enough. I'm still investigating how the fitment issues are due to model tolerances versus print methods (all parts require supports).
The set with parts numbered "4" splits the barrel to reduce support usage on the barrel, but adds a seam through it. I haven't had time to print this version yet, though it should in theory fit together better.
