A patron requested a replica of this wheel, so we made one. Should be accurate down to about 0.1mm or so, but also keep in mind that the dimensions are as-is, there's no additional clearance worked into it other than what the original had.

I will ask the patron if they know the model name/number for this particular toy, so I can add that info later. I will also add a pic of the 3d printed version once it's been made. Left object is original, right is 3d printed replica.
