I have a klipper installed, so the screen on my anycubic is no longer functional, but it is always on. I decided not to turn it off, but to use it as an indicator for turning on the printer.
I glued it on b7000 glue. You can use thermal glue or double-sided adhesive tape.
Print with the filling so that the part does not show through.
I recommend using the Hilbert curve as a template for filling the upper surface.
