I came across pics of someone who wrapped their 2 Wall Chargers in carbon fiber like vinyl. His and hers wrapped in colors to match their Teslas. I’m not sure how they printed Tesla on the wrap but it came out nicely.
It looks great, at least a lot better than boring grey. Not a huge fan of fake or functionless carbon fiber either, but it's not on the car after all.
I think the plastic face removes fairly easy, so another option is to just spray paint it.
