I 'dismantled' one once. When I say dismantled, I mean destroyed. I had separated as in t-cut's picture above, withdrawing all the gubbins inside. The plan was to mount a USB socket into it. I had drilled it with the domed part still attached to the 'backing' of it. Once it was drilled it was flexible enough to pull off (by that stage I had given up on the idea). From memory it prised off, but with difficulty, and as I said it had the centre drilled out of it, so could be flexed. It will come off, but it will be on very very tightly.
