Description

Summary This is a quick customizable way to make an array of columns of any size and with any size columns. This little design is a great example of the beauty and power of OpenSCAD as it has lots of uses -- everything from setting up a 3-D printable plinko game to using them to make holes in your Buckner funnel (which I will post in a moment) to illustrating the geometry of your semiconductor nanocolumn array to optimize their optical properties for solar photovoltaic applications (see for example InGaN nanocolumn paper (http://www.academia.edu/1484579/Effects_of_Substrate_Temperature_on_Indium_Gallium_Nitride_Nanocolumn_Crystal_Growth) By the [Michigan Tech's Open Sustainability Technology Research Group](http://www.mse.mtu.edu/MOST (http://www.mse.mtu.edu/MOST)).
