I modeled this to resemble the faceplate that comes with Zeb's plunger, which seems to be based on some generic Bally/Williams faceplates. The dimensions don't match up exactly with Zeb's faceplate, but I feel like I got close enough. Some websites call this a Ball Shooter Housing.

I wanted a T2 faceplate to match the Terminator 2 theme. Should be compatible with zebsboards v5 plunger. I currently have one painted and installed on my cabinet. The ribs that end up printing are not in the original model, and are an artifact of trying to 3d print that gradual slope. You might be able to re-arrange the model in another orientation that hides or removes most of these. You could also try printing at a finer resolution. For my use case, I feel like the ribs added an industrial look that fits well with the theme, so I kept it that way.
