They break overtime and there is no replacement part for it. There is a file on thingaverse to 3D print one. I’ve went that route and it was a no go. Was way to big and needed sizing down. On Facebook a guy posted the other day about going to the auto parts store and finding a rubber grommet that fits the hole perfectly. It might not be grey or silver but it is by far the best replacement I have seen so far. Here is the box and the look afterwards. The spaceball part should be taken off for instillation.
