Any thoughts for custom-sizing a thin glass sheet to protect an LCD screen? (self.askelectronics)

So my wife cracked the screen of her Playdate console. I got a replacement memory LCD (Sharp LS027B7DH01A), but the LCD is mounted with optically clear adhesive directly to a piece of glass which is adhered around the edges to the console’s faceplate.

The glass measures 65.15x41.64mm by 0.65mm thick. Definitely not a standard size. I can’t find anywhere to buy glass so thin and so large.

My first thought was to cut a phone screen protector down to size with a glass cutter. My first attempt failed because the screen protector I bought was actually coated in plastic on both sides. Even if I got a straight cut, I couldn’t find a way to slice through the plastic layers cleanly.

Any ideas on where to find cuttable glass sheets this thin? I could try more screen protectors, but there’s no way to know if they’ll work before buying them.

I might. I already emailed them for another project asking what model screen they were using, and they refused to share that info, so I don't think they're too open to hardware hobbyists.

The other project was adding a light. There is a vendor that offers a front-light for that model, but it's like $60 and the result is too thick to fit in the stock Playdate.
