About this 3D model

Shows the angles in degrees and radians. Does not have sines and cosines (the coordinates). Features raised quadrant lines for ease of use. I began designing this before the math manipulable challenge and finished it afterwards. D: oh well. NEW: I'm thinking of offering this for sale on Shapeways! Tell me what you think! New news: I fixed. I'm so so sorry for anyone who may have tried to reference this.
