This is the red nubbin on the side off the 1989 Kenner, The Real Ghostbusters, Ghost Trap.

I have modeled this off an existing, intact, nubbin. This will allow you to print off a replacement to restore the toy.

I am not sure what this part is supposed to be. It could be a light, a button, or just some other geometry. Since I am not sure, nubbin will stay.

There are 2 versions of the part. The replica part is as accurate as I can make it and retains all of the geometries. The easy part looks the same on the outside, but all of the internal geometries that were molded in for material-savings / manufacturing have been filled in. In this case, the base of the part is extended all the way to the end of the stand-offs to make the print simpler while not impacting the look of the assembled trap.
