This is a cover that will fit over the LCD screen of the Anet A8 that uses the 5 button display. It may fit models with the knob display, but I am not sure.
If your frame messaures different than 8mm thick, then you will need to scale this to fit.
Included are two versions. One with lettering that looks better, but is harder to print (if you print with support it is very hard to remove from the letters). And, one that is thicker with no lettering for maximum light blockage and easy printing.
