Wow! Your lucky he shed in one big piece. My girl usually sheds in many small pieces which is a pain to clean up after. What type of substrate are you using??
It was a few big sheets with the odd piece here or there but way less pieces and easier to clean then last time. I'm using Reptile prime and sphagnum moss mix and keeping humidity over 80% most of the time which should be easier once new enclosure is done.
