Review on Mach5 Screen Saver Protectors for Printers by Frank Harwood

They do their job. But with how technical it is 3D printing. The presence of something that disrupts or alters any movement or process. It would be much better if they came with cut out design for different size printer LCD screen. I don't want to guess when cutting, so I glued the entire sheet. It overlaps a lot and I had to re-level my build plate. But the annoying thing is that it sticks to several of me and pops up after each push. So I have to recycle air bubbles to avoid print quality issues.
