Printer Calibration; Spaces and Fill (Q42096)

I created this model to speed up how I go about calibrating my Thing-O-Matic and associated skeinforge settings. It consists of the following parts: - One comb-shaped structure aligned on the X axis with teeth spaced 0.1mm to 1.0mm apart in 0.1mm increments. - One comb-shaped structure aligned on the Y axis with teeth spaced 0.1mm to 1.0mm apart in 0.1mm increments. - One short square for checking fill algorithms. - One 608 bearing scale ring (OD: 22mm, ID:8mm, Height: 7mm) for checking inner hole diameter.
