Parametric Funnel – Custom Fit for Any Container

This is a fully parametric 3D printed funnel designed so you can easily adjust it to fit your exact use case. Whether you need a wide funnel for pouring liquids, a narrow one for small bottles, or a custom size for workshop, garage, kitchen, or hobby use, you can change the dimensions directly in the parametric settings.

The design includes a clean tapered shape, a practical hanging hole, and reinforcing ribs for extra stiffness while keeping the print simple and efficient.

Adjustable Parameters

You can customize:

Pouring Diameter – controls the width of the top opening
Funnel Height – adjusts the overall height and taper
Funnel Thickness – changes wall strength and durability
Container Hole Diameter – controls the outlet size
Lip Distance – adjusts the outer rim size

This makes it easy to create a funnel that fits different bottles, containers, jars, canisters, or workshop needs.

Features

• Fully parametric design
• Customizable top diameter, outlet size, height, and wall thickness
• Built-in hanging hole for storage
• Reinforced side ribs for better rigidity
• Simple functional shape
• Great for household, garage, workshop, and hobby use
• Easy to resize for different containers
• Clean print with practical geometry

Print Recommendations

Recommended material: PETG ( for fuel or anything similar). PLA for lighter use 

For general household use, PLA works well. For garage, workshop, outdoor, or warmer environments, PETG is recommended.

Suggested settings:

• Layer height: 0.20 mm
• Walls: 3
• Infill: 10–20%
• Supports: Not needed
• Orientation: Print upright with the large base on the build plate
• Brim: Optional, useful for tall narrow versions

For liquid use, increase wall count and consider slightly higher extrusion or post-processing if you need improved water resistance.

Notes

• Since it is parametric, make sure to check your selected dimensions before printing, especially the outlet diameter and wall thickness.
• Unrealistic dimensions breaks the model. If that happens to you, change some of the parameters. Especially Pouring Diameter and Funnel Height needs to be somewhat close to each other
• For food-related use, please use food-safe filament and follow appropriate safety practices for 3D printed parts.
