All models are designed to print flat and without supports or rafts. All files have been run though NetFabb. I printed these in PLA at a resolution of .1mm.
I found a good deal of inspiration from Talismancer's bar: http://www.thingiverse.com/thing:1194408
Each individual section of the bar has 3 files. A Bottom, a Top, and a Front. The parts with a 1, 2 or 3 indicate a straight section of either 1", 2", or 3" in length. Parts with a 22.5 or 45 indicate the angled sections, 22.5 degrees or 45 degrees. Part with a R, L, or C indicate either Right side, Left side, or Center sections. A part with 'RL' means it can be used for either the right side or left side.
