Custom Cut Glass from LowesGetting Glass for my bed

I let my printer run last night, printing some spinners (My daughter’s classmates love them).  When I woke up this morning, I pulled off two finger pads, and the glass came up with it, like it was part of the print.  This was really odd, but I had been planning on getting some more glass anyhow.  I ended up going to Lowes and found it for $2.68 per sheet (It comes out to 10″ x 12″ x 3/32″, or right around 3mm).  I then had them cut it to size.  I am using these corners from Thingiverse.  I printed 4 of the wire holder versions since they had longer edges.  Using the bed measurement based on those edge holders, my bed was 8 5/16 x 10 11/16 or 233mm x 273 mm.

I like having multiple pieces.  I would say 2 minimum, 3 or even 4 being more optimum.  With 2, you can swap prints off while it is still hot, and let the glass cool off the printer.  The printer can print on the new sheet.  I have run into issues where I had a failure that I was able to reslice and continue from.  Having a glass plate that can come off and be put back on is nice.  Also, make sure you always put the glass in the same way, for this to work.  

Previous to this, I was using glass from a frame I purchased cheaply at Walmart.  This custom cut glass ended up being a better price, plus fits better.  I wish I had realized this long ago.

 Maker Glass

While my personal recommendation is cheap glass that I mentioned above, I think I should mention that you can also get Maker Glass.  This is Gorilla Glass for your 3D Printer.

Hairspray, for grip

On top of that, I am using Aqua Net Extra Super Hold – Unscented on the glass to help stick my prints to the glass.  For the most part, this works really well.  (and from the beginning of this post, you can see it can work WAY too well.  So, while it sucks that I had to replace the glass… (or, well, turn it over), it ended up being a blessing in disguise.  I can now pull a print off the bed, and leave it on glass to cool down, while I have another sheet of glass ready to go and print on.  

While I went to Lowes, I would be very surprised if other large hardwood stores didn’t have similar capabilities as similar prices.  After having used a smaller piece of glass for two months, I really wish I had realized how truly inexpensive buying glass at a local store could be, let alone one that is cut for my bed!
