Universal spool hub 52mm - 18.7mm

My friend was so impressed with the turn around time of his taulman hub, http://www.thingiverse.com/thing:965837, that he said, "hey you're getting good at this!"
To which I replied, "Yeah, I feel like I'm getting the hang of this."
His next response was, "It would be cool if this looked like the rims on my car..."
I should have said, Challenge accepted!
Instead I asked for a picture.
A bit of messing about, and I came up with this. To which he replied, "You are mad."

Yes, thank yo
