The Afinia H479 and H480 (I have one of each) comes with perf-boards to print on. These work fairly well for most purposes, but the boards warp with the stresses of cooling plastic layers, and it’s difficult to print something with a wide bottom that is truly flat, but this is often necessary.<\/p>\n

Luckily Afinia also sells sheets of Borosilicate Glass that clamp down to the heated print bed. Alone they do nothing, but when the glass is coated with a thin film of ABS slurry (a mixture of 10% bits of ABS plastic and 90% acetone by weight) something actually magic happens: The print sticks to the unwarpable glass like crazy, and then when it cools, it pops up as if it was almost never attached. I mean I have no idea how this works, but man, it works!<\/strong><\/p>\n

I bought three sheets some time ago and that’s perfect to keep a print flow going. But one of my cats knocked one over and shattered it, and I dropped one, leaving me with one. So I bought three more.<\/p>\n

Now I find that they are cluttering up my already cluttered work surface:<\/p>\n

(And this is me organized!)<\/em><\/p>\n

So I thought I needed some place to store the sheets of glass waiting to be used. I came up with a modular rack system.<\/p>\n

Since my Afinia can only print a 5x5x5 volume, and the rack base pieces had to be over 7″ in length, I cut the parts up in two halves with jigsaw tab and slot design so they can snap together. This works very well<\/strong>, snapping very tightly with perfect matching tolerances!<\/p>\n

Here you see the two halves apart,\"glass-plate-base-parts-01\"<\/a><\/p>\n

then snapped together:\"glass-plate-base-parts-02\"<\/a><\/p>\n

Screw holes on the sides allow me to screw this into a plywood wall that is just above my print table.<\/p>\n

Then I created these slotted holders that can slide into the base pieces:\"glass-plate-base-parts-03\"<\/a><\/p>\n

(I have since redesigned those a bit to allow easier insertion of the glass by flaring the apertures a bit, see the final pic.)<\/p>\n

So I printed four sets, snapping them together. Since I designed the slot system to not come apart easily, I only need to screw in the top and bottom rack bases, though I could, if I wanted, screw them all in place.<\/p>\n

This is the improved slot design. Slightly less wide, but flared so I can put the sheets in easier, yet they still hold well.\"glass-plate-base-installed-01\"<\/a><\/p>\n

And here are the borosilicate glass sheets in place, perfect, out of the way, and easy to grab when I need one.<\/p>\n
