Caleb's 2020 blades designed in TInkercad and 3-D printed. Below, see his CAD pieces on the computer screen. He used blue filament and red marking tape to create his final set of blades. Note Soren (below) working on the computer to get his CAD file ready to print on the laser cutter. His final blades were made of light weight wood.
Some KidWind Middle School team members learn how to use 3D Modeling software run on web browsers to design parts for their wind turbine. Tinkercad, founded in 2010 and acquired by Autodesk in 2013, is one program they like to use. Tinkercad uses a simplified constructive solid geometry method of constructing models. A design is made up of primitive shapes that are either "solid" or "hole". Combining solids and holes together, new shapes can be created, which in turn can be assigned the property of solid or hole. Shapes can be imported in three formats: STL and OBJ for 3D, and 2-dimensional SVG shapes for extruding into 3D shapes. Tinkercad exports models in STL or OBJ formats, ready for 3D printing.
