raised support for upper glass. not having the need to put the ams on top, but to allow the hot air generated inside the printing chamber to escape. I then added a custom-cut polyurethane gasket to eliminate any vibrations and to make the glass more stable. no one excludes the possibility of being able to put the ams on top. However, you must be careful to ensure that it does not slip because it is not a straight project, but an inclined one. rubber felt pads to apply under the ams would already be an excellent solution.
