DualVee dust cover replacement felt wipers

[jTr]

Title says it all. It's a Bishop-Wisecarver product. Just looking for felt to replace oiler/wiper inserts on X and Y rail dust covers. Anyone have a quick solution? Tried filling out their help request but it immediately delves into a major inquest into engineering your next project... Is it really this complex to get a few tiny cubes of felt? Everyone else just buying sheets and cutting to fit?

Thanks for any help.
