sxt173 replied to c-ernst's topic in Modifications, third party add-ons & other hardwareSorry for the late reply, I totally forgot to click on "notify when reply posted". Yes, that is where I got mine. They are pretty quick and I got it was exactly as ordered. I like them because they specialize in one-offs and they do ceramic (tempered) glass or all shapes, thicknesses and sizes + they can drill holes in tempered which is rare. I would advise going for tempered. It's not the actual temp that the glass rises to, but it's more about the speed at which it heats up and cools down that can cause cracks.
sxt173 replied to c-ernst's topic in Modifications, third party add-ons & other hardwareI already got a glass build surface (not for Ultimaker, no ultimaker yet actually..), but did you check onedayglass.com? They are in the US, have reasonable prices for one-offs, they do tempered (which I would highly advise) and can drill holes too.
