Say goodbye to the usual retention when single dosing, and instead get much closer to your exact dose every time*. This 3D printed flexible bellows fits in between your machine's stock hopper and stock lid and transforms it into a blower, allowing you to achieve 0.0g - 0.2g retention on every grind*.

[Design Features]

Simplicity and maximum effectiveness are our design goals, and both are carefully infused in our bellows' design.

The bellows complements the grinder's original design rather than replacing it and upsetting its visual balance
Super easy installation takes less than a minute
No tools necessary for installation
No warranty-voiding modifications needed
Zero contact between bellows and beans each time you dose
Small manual included with assembly instructions and best use tips
Bellows works even if you prefer to store beans in the hopper (though less effectively)

[Compatibility]

This bellows is compatible with:

Tiamo 700S
Feima 600N
Feima 610N
Several Tiamo and Feima models with the same hopper design, with a hopper top diameter of approx 10.5cm
More confirmed models coming soon

[*Disclaimer]

Grinding after changing grind size or using darker roasts/oilier beans may still cause some retention
Achieve the best results with lighter roasted beans and at a consistent grind size setting
The coarser you grind, the more likely you'll achieve zero retention
The more beans you store in the hopper, the more possible retention there may be
Does not include the grinder nor the stock hopper
