Customizable button generator (infinite shapes)

Have you ever needed a specific size, color or shape to finish a sewing project, but the stores were closed? This parametric generator is the ultimate solution. With a few clicks, you can generate a perfect replacement or a complete set of custom buttons for cardigans, bags, and craft projects.

This is a fully parametric OpenSCAD engineering tool that dynamically generates 10 distinct complex geometric shapes. The algorithm utilizes advanced trigonometric functions (sine/cosine loops) to calculate star patterns, and executes complex union() blends for organic shapes like hearts and flowers. Furthermore, it computes proportional boolean subtractions (difference()) for adjustable sewing holes via rotational matrices, and utilizes negative mathematical offsets (offset(r = -act_rim)) to procedur
