I was printing some ABS on my modified Anycubic I3 Mega overnight, when I awoke to this horror of a destroyed glass print bed...

Now the question remains, how to actually fix this? One part is still firmly attached to the Bed and I fear this may destroy the Bed even more.

And I obviously need a new Print bed, but I can't find the exact replacement, so should I even get a replacement Ultrabase? I saw that there are magnetic PEI beds available, but I am unsure if it is worth the 80-100€ for this.

Edit: Since the glass is glued to the 1.5mm aluminium heater PCB (and I already had to resolder the broken off wires once) I was looking at complete replacements at first, which why the price is relatively high
