I have a monoprice select mini V2 and would like to install a glass bed.Machine came with a black bed installed over aluminum bed,do I need to remove this first or can I just install over top of original.If I need to remove what is best way to do so?

The glass goes over the aluminum one and is usually held on with binder clips. Don’t forget to print a z-spacer before adding the glass. I did this a few months back and it’s great!
