I will check back in a few mins then. The rep from there said they were out of most of them and for some reason several showed up as in stock. I was thinking going larger like you suggest to get an extra. I will ping them first and ask.
I almost pulled the trigger on the Borosilicate glass last night but I dont want the size that is a bit too small or the size that is just over-sized so I am trying to source one that is the correct size for the QIDI printer.
