Shower Screen Hook - parametric

I was inspired by takigama's hook, http://www.thingiverse.com/thing:28075, so I needed one to fit my shower.
I decided to push myself a bit in my SCAD learning and came up with this. I like the Debug concept to help visualise the bits & pieces.
Now hanging a radio, back brush, face cloth, towel (on outside of course).
The camera didn't cope well with the white plastic...ghost hook?
