iCrowd Newswire - Nov 25, 2019


Having a cup of freshly brewed coffee is a pleasant experience. To extend this experience outdoor, we never expect to carry a bulky coffee grinder. To make coffee grinding easier during camping or any outdoor activities, we designed a compact grinder that can fit in your pocket.

Nutshell is designed after a thorough research of different existing grinders
Your ultimate coffee grinder for camping

 Let’s celebrate our success with the new color version!

New reward available: The exclusive Robin Egg Colored Nutshell

It holds up to 18 grams of coffee beans for each load,which is enough for brewing 2 cups of coffee (2 x 8 oz). The bottom container can hold 36 grams of ground coffee.

Brief Instruction


Compared with other coffee grinders, Nutshell shares the grinding effort with both hands, whereas grinding with traditional ones lead to the dominant hand fatigue very soon.



With only 138 gramsNutshell weights 50% less than a generic hand grinder.


Without the need of a handle, Nutshell occupies less space than other grinders. It is convenient to be put inside bag, carry pouch or even pocket. For heavily equipped campers who would like to enjoy fresh coffee brewing at the peak of mountain, Nutshell is an ideal choice.


At the early stage of concept generation, we sketched and explored many possible forms. After CAD modeling, a variety of prototypes were 3D printed for different tests to ensure the performance of coffee grinding. By optimizing the structure, we produced molded prototype for final testing. As the design and testing procedure of Nutshell is finished, we would like to gain supports from kickstarter, so we can bring the ultimate portable grinder to the market, and share the joy with all coffee lovers!

This silicone spout is a reward from DripDrop.Cafe, which will be included in Super Early Bird Pack and On The Go Experience Pack. Goosi is a flexible spout that can be attached on any cups with diameter between 75-90mm. As it refines water flow to a narrow stream, any cup can be turn into a goose-neck kettle for making hand drip coffee.
