This is a model of the wheels off the 1989 Kenner, The Real Ghostbusters, Ghost Trap.
I have modeled this off an existing, intact, wheel. This will allow you to print off replacements to restore the toy.
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 half part is the part, cut in half, to make printing easier. The half part will need to be printed in pairs and glued together. There is a very fine mold line on the actual wheels where the two halves of the mold came together. If you are looking to make the replacement part as close as possible to the real thing, this may be the part to print.
