I repurposed 2" electrical box knockout seals purchased from home depot to make these center caps for a set of rota d2 rims. They will likely fit other rota rims and other makes of rims with the same size hole. This was my temporary solution and I've since made another set more to my liking. So, I'm selling these for $25 shipped within the contiguous US.
