I've upgraded the Anet A8 LCD display to the display from the Anet A6.
(if you want one, search on aliexpress for Anet A6 display)
I replaced the original knob with this one: https://www.thingiverse.com/thing:2449940
This upgrade improves a lot on the original display, the 5 button display is quite bad to operate.
This frame was designed to be a press fit onto https://www.thingiverse.com/thing:2267628.
With this frame the LCD is more protected and also I think it looks nicer.
There is a 0.5mm inside gap to accommodate a 0.4mm thick clear plastic sheet (aprox. 78mm x 51mm) that will protect the LCD.
The sheet should be cut to be a press fit, the edges must be rounded to fit.
I got the 0.4mm clear plastic sheet from a piece of package from a toy, I bet you can easily find it on a similar package.
I've printed it with the tabs pointing up.
If you use a glass coated with hairspray you will get a glossy finish on the show side of the frame.
