This lightbox printed beautifully. I recommend that you spray or butter the print bed and watch carefully to ensure the initial layers are going down well and check on it periodically. My first attempt was a mess because my bed wasn't clean and the bad adhesion caused it to drag everything around and just became a clump of PLA. I bet if I had been checking on it I could have nipped it off and saved the first attempt, but second times the charm! Enjoy!
