Here's how it goes - Hubs fit 1/16 inch rod (designed for 2.5mm hole)\r\nCut three pieces of black foam, each five millimeters thick, then hot glue them together and drill the hole to match the hub.\r\n\r\nNext, I hot glued the hub into place within the wheel.\r\n\r\nTo seal the exposed foam on the wheel, a thin layer of Gorilla tape was applied around its outer diameter.
