Version 2.2 | Late 2024 - 2025
v3 Auger - Slow Feed
This design feeds one bean into the grind chamber at a time. This design optimizes grind uniformity, leading to higher clarity and maximum flavor expression.
v2 Maintenance Tooling - Wera Kraftform
The Wera Kraftorm screwdriver features improved tooling quality and durability with an ergonomic design.
v3 Dosing Cup - Anti-Retention Design
The v3 dosing cup minimizes the amount of grounds leftover in the cup in addition to an improved overall look and feel.
v3 Funnel Cap - Dosing Cup Compatibility
We increased the size of the funnel cap to match the diameter of our dosing cup. This increased the amount of beans that could be loaded into the hopper.
This allows users to place the funnel cap on the dosing cup, turning it into a de-facto shaker cup.
Version 2.1 | Late 2023 - Early 2024
v2 Auger - Medium Feed w/ Teeth
This medium feed auger featured more pronounced ribs and notched teeth, improving overall performance and results.

This burr carrier featured upgraded high-strength magnets, securing our blind burrs in place without the need of set screws.
v2 Stand - Inlaid Magnet
This streamlined design made the magnet flush with the bottom of the grinder, improving magnet durability and integrity.
v3 Chute - Anodized Single Piece Chute
The anodized single piece chute was more durable and better performing than the previous 3d printed insert design.
v2 Antistatich Tech - Ionizer Removal
Our anodized single piece chute outperformed the ionizer in side by side testing, allowing us to improve performance while simplifying the grinder design.
v2 Back Plate - Stainless Steel
The stainless steel backplate allowed users to access the inner components more easily and improved the overall grinder aesthetic.
v2 Funnel Cap - Stainless Steel
Our stainless steel funnel cap featured a brushed finish and heavyweight feel.
v1 Magnetic Portafilter Holder
The magnetic portafilter holder features a universal design that allows users to dispense grounds directly into their portafilter basket.
