A parametric funnel you can customize directly in your browser. Enter your dimensions and generate a funnel that fits your exact needs. No supports required.

Model Highlights:

• Adjustable dimensions – fully customizable with just a few input parameters
• Optimized for easy and reliable 3D printing without supports
• Choose filament material according to the fluids you plan to use the funnel with
• PLA Silk is not recommended for prints where strength is required

Available Parameters:

• rim_diam – diameter of the funnel’s top edge (inlet opening).
• collar_diam – diameter of the collar below the rim (stabilizing ring).
• stem_len – length of the funnel’s stem (narrow outlet part).
• shell_thickness – wall thickness of the funnel.
• collar_height – height of the collar below the rim.
• stem_diam — inner diameter of the stem (outlet opening). The outer diameter of the stem equals stem_diam + shell_thickness x 2.
• hanging_loop_diam - diameter of the hanging loop opening (for hooking onto a nail, hook, or pegboard peg)

Material Notes

Choose your filament based on the fluids you plan to use the funnel with. PLA works for dry use and water. For oils, solvents, or chemicals use PETG or ASA. PLA Silk is not recommended where strength is required.

If you print it, please leave a make or rating. It helps a lot.

Update 12/05/2026: Fixed stem_diam parameter, it now represents the true inner diameter of the stem (outlet opening). Previously, the actual inner diameter was stem_diam minus shell_thickness x 2. If you used earlier versions, increase your stem_diam value by shell_thickness x 2 to get the same physical result.

Update 14/04/2026:  Added new model with hanging loop.

Update 23/08/2025: Changed base shape from half-sphere to cone. The previous variant was causing print errors at the connection between the rim and the spout.
