3Dprinter

Overview A 3D printer can create many things, one use that appeals to me is creating a 3D printer from scrap parts that is useful enough to print parts for a better 3D printer. That is, bootstrapping the process of creating a good 3D printer, without having to have access to one to start with. So this page is initially just going to be a collection of links to other useful pages.

[Cone icon by Fornax, CC-BY-SA 3.0, wikimedia commons] The proposal is for a machine to help recycle domestic batteries by sorting them into Zinc/Carbon, Alkaline, Lithium, Nicad, Ni-Mh categories and with a theme of sustainability/recycling the machine discharges any cells that have residual charge into the machine to power it.
