Angular Calibration Items (twisted cube and pillar)

I Created These Models to Test My Makerbot 2X, Which Was Being Uncooperative. It's Ideal for Verifying Sharp Corners and Flat Surfaces. The OpenSCAD File Pictures Appear Distorted and Hollow, but This Isn't Actually the Case When You Render Them! Here's How I Designed This Model: I Linearly Extruded and Twisted a Square in OpenSCAD with Low Resolution (Between 2 and 6 Slices) to Achieve an Angular Shape Rather Than a Smooth One.
