The glass can be mounted using the smaller holes, e.g. by some small wooden piezes having a 3.2mm hole.
The glass plate should be 22x24 cm to fit in there. The sides will overhang, but I could not find larger double sided FR4 PCBs than 30x20cm.
I also recommend to diagonally cut away the glass corner over the minx-miny corner, where the pcb has the dent, to have initial through-extrusion also with the glass. A 2cm hole in the glass would also be the possible if you don't have a second extruder..
The image is of the previous version, which cracked the glass. I will change the images asap.
