I needed an exact reference model of this bargraph so I could design a custom PCB for it, and also design a custom mounting plate for a Ghostbusters Ghost Trap build. This is what I put together in FreeCAD (using the Barmeter datasheet verified against a real bargraph using digital calipers) .

Probably no reason for anyone to 3D print one of these (go ahead if you really want to), but it's pretty useful to import into PCB design software.
