A full size, 3D printable version of the hand grip from the Ghostbusters' Proton Pack proton gun. I will be publishing parts to allow an almost fully 3D printable thrower to be made. The only none printable part will be the handle tubes, which should be made from 1.25" PVC tubing. My version of the grip is in two parts, one of which is concave to fit around the front/rear tube of the proton pack. The stl file included is for a tube of 1.25" outside diameter. The openscad file included allows the base to be changed to match the tube diameter of your choice (within reason). The scad file allows the base to have a cable channel within it. Change cableChannelDepth to 3 or 4 for a most applications. Grip dimensions are approximately 120mm long by 38mm wide by 35 mm high.
