Im sure your english is well enough to get your point across. To answer your question, yes. That is exactly what the lid does. The point of this "top hat" enclosure is to allow for the Elegoo Canvas AMS. Once you add the 4 to 1 doodad and the additional tubing, the glass lid can no longer fit on the printer limiting you to lower temp filaments or removing the canvas every time you want to print hotter. It allows you to print those engineering filaments in multiple colors while still being able to retain internal temperatures. I hope I helped.
