OpenSCAD (Required for the Maker)

Today after finishing the prints for the parts I need for my 3D printer model, I realized I had made a huge mistake. I hadn’t checked the measurements for the holes / rods and since I had gone with the US alternatives to the metric measurements, some parts just wouldn’t work. DOH!

This led to my next realization. The open source community provides the files in easily configurable SCAD files not Autodesk files or STL (STL would have been alot more difficult to edit although it can be taken and printed immediately).

In case you didn’t know, the beauty of SCAD files is that they are essentially programs. OpenSCAD is pretty much the open source standard for creating 3D objects before exporting them into STL format. It is a functional description Red and Yellow Cubes SCADlanguage that dictates the characteristics of the object that allows for reusable variables and one configuration file with the power to change your whole print library! Here’s an example that creates these two rectangular blocks:

If you have been reading my blog posts, I had started using Autodesk Fusion 360 and I thought it was one of the best programs for 3D modeling. Little did I know that the open source community didn’t hand out files consumable in Autodesk and the power behind SCAD files in the open source community is how easily the objects can be customized especially since altering a bunch of STL files would take serious time in Autodesk Fusion 360.
