This is a trap door off the 1989 Kenner, The Real Ghostbusters, Ghost Trap.

On these old toys, it is not uncommon to find the doors with the engagement pins broken. This will allow you to print off a replacement to restore the toy. I have modeled this off an existing, intact, door.

I have also made inverted doors, in case you wish to change the pattern of the stripes on your doors. CAD files are also provided.
