I tried following the official first draft of the assembly video, but then switched to Anuvin's version. There is a fine art to keeping your hands in the frame of a how-to video while talking about and apparently showing the audience key parts and their orientation on the assembly. Also the scanner portion was a bit hard to watch... Hot glue for paper, really? I can't complain about the scanner though, it was basically a freebie along with the printer.

As for the build reservoir, I found a better container to use than a pop bottle. My wife's favorite drink:
Attachment 8493
Still 2 liters, but the plastic is maybe 50% thicker and completely straight sided.
