You asked for a shaker so here's my version of it.
Key Features:
Cap and plug are friction fit and won't fall off
Cap and bases are magnetic, using the same seamless hidden magnets like my funnels
With the base screwed on, there is a 30mm "funnel" drop height to allow the grounds to come together as they are released
Mesh filters included have a 150µm, 250µm and 350µm rating and are made from stainless steel. They are retained by a magnetic stainless steel ring. Filters and retaining ring are not required to be installed
Slider is easily adjusted to fit most grinders or removed entirely if not needed. The shaker body can be shifted up to bring it closer to the grinder's spout. It is machined from acetal to provide smooth insertion. Your grinder's metal forks will glide across the slider rather than chew up the anodized aluminum body. As some of you have asked, the Shaker Funnel is now available without the sider
Bases are interchangeable and are currently available in 49mm, 54mm, 55mm, and 58mm
Available without a base if you're looking for a more compact design or just don't need it. With the base removed, racking marks may be visible on the underside as part of the anodizing process
If you are using the Shaker Funnel alongside a dosing funnel, it is recommended to still use a base as it helps center the Shaker to the funnel
Additional magnetic bases are available separately here
Other considerations:
Shaker is 95mm tall without the cap (including the plug) but should fit most grinders. If needed, the magnetic base can be removed, making the total height only 78mm
Slider height can be adjusted between 36mm from the bottom and 6mm from the top - or 20mm from the bottom with the magnetic base removed (measured to the top side of the slider)
Notice:
Due to high demand, there may be delays with order processing and may not arrive before Christmas. Please use UPS 2-Day for best chances.
In order to streamline orders at this time, all shakers come with 58mm bases. Other size bases are available separately here
