I did it all the time, Just take times and let it get soft before take it out.
The best way is to cut it first and use the hack saw blade to cut the inside into a few pies, then heat it up and use a needle nose plier peel it off one by one.
if you understand what I mean it should work, if you are in NJ you can shoot me a PM and stop by one day I can help you take it out.
