Post-Printing

• Allow the model to cool completely before removing from the build plate.  Springs will lose memory if exercised when still warm.
• Use due care removing the model from the build plate, the pocket door spring is fragile until released from the build plate.
• Before closing the cover, push the latch inward and/or upward to break the spring free from the internal supports.  Then open and close the cover several times to smooth operation.
• When opening the pocket door for the first time, push on both the door and the slide simultaneously to break it free.  I've not had issues with the latest versions, but this may prevent breakage.
