Dental floss is your friend.

Having trouble removing your prints from the bed? Pry at least one corner up off of the print bed. Grab some dental floss, wrap it around your fingers leaving about 8 inches (depends on size of print) and slide under the print. With a little muscle it should easily pop off, avoiding any damage done to the print bed due to prying. http://ift.tt/2nf5h87
