Worked great! I was looking for a way to easily upgrade my glass heated bed on my TAZ 6 (incrementally upgraded from a TAZ 4). The prints would stick well to the glass bed but was such a pain to get them off. Got this 300 x 300 adhesive magnetic sheet and applied it directly to the glass (let it cure for like 3 days). I ended up getting a spring steel sheet from Lulzbot to magnetize to this, since I wanted a textured one. All the sizes matched up perfect and I am really happy with this upgrade!
