Looking for different size "wheels" for a roller based rotary

I’m looking to find where I might buy different size “wheels” that hold an object in a roller based rotary. My current setup doesn’t allow for conical objects like some glasses are.

If you have a makerspace nearby or desire to contact an online 3D printing service, you can have wheels made to your specifications.

Do they use O rings on those wheels?

A picture could help. 3D printing is a good choice, but at least we would need to know how they are attached to your rotary.

Here is a closeup pic of the rotary.

Harbor Freight sells assortment boxes of O-rings. Pretty easy to custom make wheels of whatever size you need.
