Look for metal beaded plugs

I’m looking for a gradient metal beaded plug/dildo like this [Beaded Plug](I’ve found a few, but the largest diameters tend to be relatively small. I’m looking for something between 1.5 and 2 inches (40-50 mm diameter) at the largest, preferably with a machine attachment. I’ve looked everywhere, but can’t seem to find anything similar.
