After messing around with the Print Bed for a little bit, I figured out a few things: The four covers on the top that are covering the screws that sandwich the heater to the aluminum underside are glued on. They will also bend if you try to pry them up. So there will be no removing the heater. I guess we can just throw the whole thing into the freezer, remove the PEI, use Goo Gone/Acetone/Limonene to remove the adhesive. Since the PEI sits directly on the aluminum, it should be a lot easier. Hoping to try this on Thursday when my adhesive transfer sheets arrive from Amazon (bought the PEI but forgot the 3M sheets).
