Thought I'd share this small discovery with my fellow BigBoxers. I clean my build plate after every print, and I've found that glue stick (I prefer Elmer's Xtreme to UHU) gives me the most reliable adhesion with the least hassle. A few days ago I needed to print an object 158 X 254mm by only 4mm tall, and had some serious doubts about getting it off the plate after it was done. I tried to get a scraper (I use palette knives: they're thin, springy, and don't have sharp edges or corners) under it, but no dice. Thought about using a heat gun, even if it meant sacrificing the print, but then hit on the idea of tossing it in the freezer instead. After about 10 minutes I pulled it out and heard crackling noises as the print began to release. It slid right off without any effort on my part. Feel free to tell me if absolutely everyone already knows this trick, OK?
