Funnel Generator - Parametric Fluid Funnels

Looking for Funnels? Look no further.
 

This OpenSCAD script allows you to generate fully parametric funnels with customizable geometry and features. Whether you need a simple kitchen funnel, a fast-pouring workshop funnel, or a lab funnel with air vents and fins, this script lets you design funnels tailored to your needs.

🚀 Quick Start

Create your funnel in no-time. Here’s how to get started:

1. Define Your Funnel
   Set the overall size by adjusting funnel diameter, height, and wall thickness. Fine-tune the spout length, taper, and tip cut angle to control flow. All dimensions are in millimeters.
2. Customize Your Funnel
   Enable a brim for extra stability, add a hanging loop for storage, or activate exterior channels to improve pouring speed. For extra control, add internal fins to guide flow and reduce turbulence.
3. Export & Print
   Once customized, generate the funnel and export it for slicing. Choose PETG for chemical resistance or food-safe filaments for kitchen use. Increasing wall loops reduces infill in tight areas, giving stronger, faster prints with smoother walls.

⭐ Features

• Fully Customizable
  Easily configure every aspect of the funnel, from spout shape to vent channels.
• Speed Channels
  Add exterior channels to prevent vacuum seals and improve fluid flow.
• Interior Fins
  Optional fins guide liquids, reduce swirling, and help with filtering.
• Precision Modeling
  Generates clean geometry and accurate dimensions for reliable prints.

🛠️ Changelog
