How crafty!
However, I have the Samsung dock and I can't see grinding it up, plus it's back is taller and contoured...I guess I'll have to choose the lesser of evils
For my dock, it was the sides and bottom thatneed the slight grinding(and when I say slight I mean 1mm possible 1.5mm of material removed.
I just shaved off the amount needed, then went back with a sanding disc and polishing disc until it was smooth(so it wouldn't scratch up my case)
