Gear Pipe

youmagine

This pipe is designed to hold a rolled cigarette or a small amount of smoking material in its larger end, while the smoker's mouth fits around the smaller end. Please use this accessory only in legal circumstances and as a novelty item. The gear design consists of seven gears with varying numbers of teeth, ranging from eight at the mouth end to fifteen at the material end. You can customize the shape and opening sizes using the OpenSCAD file provided. Note that setting the value of cp=3 is nearly minimal for passing ShapeWays design requirements, which affects the number of teeth possible for a desired opening diameter at either end. To purchase this pipe from Shapeways, visit https://www.shapeways.com/model/2995740/gear-pipe.html?li=aeTabs and I will receive a 10% profit above material cost. The total cost is $42.76 if you buy it from my account as of January 2015. If you prefer to set up your own account, use the included STL file or another design from the modified OpenSCAD file to save 10% of the cost. Either way is fine with me! Please note that Shapeways does not list their products as food safe - this product is intended as a collector's item and a novelty only.
