A customizable sheet of the most common chainmaille weave known: European 4 in 1.Open in customizer to generate your stl file for printing. Sometimes the customizer does not launch correctly. If this is the case, follow this link: http://www.thingiverse.com/apps/customizer Also, if you plan on printing really thin rings, I would suggest rotating the model 45 degrees so that the rings are either vertical or horizontal. Of course you would need to add support as well. I have successfully printed 2mm diameter rings on a diagonal with a makerbot.
