This model is known worldwide, featuring at 1:54 in the Robot Hospital episode on this YouTube video: http://www.youtube.com/watch?v=shpt1hD4z7Y. It's blogged here: http://www.makerbot.com/blog/2011/06/23/wall-thickness-calibration-test-piece-by-miserybot. This tool is used to analyze your Skeinforge settings and MakerBot performance for various wall thicknesses: 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.2, 1.4, 1.6, 1.8, and 2.0. The OpenSCAD code is provided for experimenting with additional thicknesses. The image displays the intended wall thickness in green, the actual straight-wall thickness after printing in red (for the user's bot), and the measured cylinder thickness in purple. With a 0.25mm layer thickness and W/T ratio of 2.0 for calculated wall thickness or 0.5mm, this model is compatible with MakerBot 0.4mm nozzle, although it doesn't significantly impact the result.
