Customizable Funnel Generator

Stop searching for the right funnel size. Whether you need a tiny spout for pouring 3D resin back into a bottle, or a massive wide funnel for car oil, this generator creates the exact fit in seconds. Unlike other models online, these funnels are completely smooth inside without annoying designer names embossed on them that trap dirt and fluids. The handle is deeply embedded into the wall and features a fully enclosed, perfectly centered hanging hole for maximum strength. 🧠 Behind the Design (For Makers & Moderators) This is not a simple primitive shape extrusion. This fully parametric OpenSCAD tool utilizes complex dynamic 2D-to-3D hull() transformations to calculate a structurally reinforced handle profile. The algorithm uses mathematical constraints (e.g., min() functions based on cone height) to deeply anchor the handle geometry directly into the conical wall parameters, ensuring it generates as a unified, high-strength manifold solid. Furthermore, it employs precise boolean overla
