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

If you want a cheap solution, just get a mirror in the same dimensions as your bed but I am pretty sure you could find a PEI bed for less than 100 if you keep looking.

In the future, if you stick with glass, don't print directly on it with stuff like PET or ABS: use a release layer like hairspray or a thin layer from a glue stick, otherwise it can bond to the glass and break it.

To be fair the PEI kit I was looking at is a aluminium baseplate, silicone heater mat, magnetic base & the PEI sheet, so basically a complete replacement of the bed.

since the glass is glued to the heater I was looking at a complete replacement at first.

Oh, that's not too bad price-wise actually.
