Achieve a lower retention on every grind* for an easier single dosing experience and cleaner grinder with this bellows upgrade. This 3D printed flexible part fits in between your Fellow Opus hopper and stock lid and transforms it into a blower.

[Design Features]

Simplicity and maximum effectiveness are my design goals, and both are carefully infused in my 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
Zero contact between bellows and beans each time you dose

[Compatibility]

- Fellow Opus

[*Disclaimer]

Grinding after changing grind size or using darker roasts/oilier beans may increase retention.
Achieve the best results with lighter roasted beans and at a consistent grind size setting.
Does not include the grinder nor the stock hoppers in the photos
