This is a standard size Badminton Shuttle. It's printed in Nylon as Nylon is a very light yet strong material. For info on printing with Nylon see: http://www.instructables.com/id/Combination-CNC-Machine-and-3D-Printer/Print in Nylon . If desired, you can cut trails in the rear cone. To meet regulation, the shuttle must be ~ 5.5 grams. Adjustments can be made in perimeter and fill to accomodate weight.
