OpenSCAD is kinda neat

The author explored using a code-based CAD tool to recreate a parameterized battery holder previously designed in a traditional CAD program. This involved writing code to generate a 3D object, serving as an introduction to the new tool's basics.

The resulting design allows customization of battery type, number of rows, and columns simply by changing a few variables in the script. The core logic involves creating an initial solid block and then using a loop structure within a difference operation to subtract precisely located, sized cutouts for the batteries.

The author found the approach surprisingly effective for this simple geometric design, noting its potential utility for creating other straightforward but practical items like spacers. A minor point of confusion arose regarding the necessary use of the let() command inside the iteration loop.
