![]() ![]() We will use a sphere, so that the hard edges of the cube will take on the shape of the sphere. to give the cube rounded edges, we call minkowski, which will trace the shape we specify around the edges. * The first object will be our main cube. ![]() We will use this to make our cube hollow. This specifies that we will be subtracting the second object we call from the first. * Next, we call the difference function. * This module constructs the main body of the enclosure. After calling those four modules, all that is left to do is split the enclosure in two and render the halves as separate STL files for printing. ![]() The four modules below construct the main body of the enclosure, arrange the holes in the enclosure for our electronic components, add a texture to the enclosure, and assemble all the pieces together. Modules also help break a larger job into more manageable parts and keep the code nice and clean. By assigning variables to parameters, you can vary the size and location of these objects easily. In OpenSCAD, you can quickly build duplicates of small parts into more complex designs using “modules”. OpenSCAD is a great open source solution for CAD and 3D printing projects. We’ve been working in Python to prepare the audio and wanted to generate the enclosure programmatically as well, ideally using open source software. We are currently creating a customized media player to allow people to interact with MP3 artifacts. This is a tutorial on how to use OpenSCAD to design a 3D object via code instead of using a WYSIWYG editor like Tinkercad, Fusion360, etc. ![]()
