A wide, clean and solid loading funnel for Timemore C3 series hand grinders.

The default ready-to-print version is made for Timemore C3, C3 ESP, C3 Max and C3S.

Use the Customize button to change the funnel dimensions and generate a version for your own grinder.

You can adjust the funnel height, funnel diameter, socket size and fit depth, so the model can be adapted for many other hand grinders with similar top-loading designs.

☕ Clean and comfortable to use

This funnel makes it much easier to pour beans into the grinder without spilling them on the table.

It is wider than many small grinder funnels, so you do not need to aim too carefully. Just place it on top of the grinder, pour the beans in, remove the funnel, put the handle back, and grind.

The default C3 version sits firmly on the grinder and does not slide around. It also feels pleasant in the hand because it has a nice weight, not a thin disposable feel.

The shape is simple, minimal and stylish. It looks like a natural part of the grinder setup, not like a random plastic add-on.

🧩 Compatibility

Default ready-to-print version:

• Timemore C3
• Timemore C3 ESP
• Timemore C3 Max
• Timemore C3S

Customizer version:

• adjustable funnel height
• adjustable funnel diameter
• adjustable socket diameter
• adjustable fit depth
• adaptable for other hand grinders

If your grinder is a different model, a clone, or has a modified top, measure it first and use the Customize button before printing.

For non-C3 grinders, the fit depends on your measurements. If the funnel is too tight or too loose, adjust the socket size and generate a new version.

🖨️ Print notes

Prints without supports.

I recommend printing it with matte filament. The matte surface looks much better on this model and gives the funnel a more premium feel.

If you are not sure about printing it in white: I printed mine in matte white, and it works and looks great.
