This thing was cracked in shipping, just around the screw hole and outside of the heated pad area, so it is just bed material and it bears load, but not very much. Essentially it has lasted for the year by being held together only by the PEI(?) print surface/sticker (and I have had glass on top). That surface is getting worn out, so I'm going to replace it. I figure while I have it off I could try to fix the crack before putting the new sticker on. Figured someone here may have a good suggestion on adhesive if they know what materials are typically used here as I am out of my depth.
