Herb Grinder with Turbine Blades, 74 mm

thingiverse

Based on TrooperOrange's outstanding work, which in turn was based on Clarkerubber's equally impressive work, I've incorporated several enhancements. 1) The bottom bowl piece is threaded to prevent it from falling off. 2) There are no 90-degree overhangs, making it a breeze to print. 3) The bowl is now deeper, allowing for greater capacity. 4) It's taller because the top had a tendency to tilt if there were too many herbs in the grinder; this phenomenon is known as cattywampus. 5) I added guide slots in the housing with matching tabs on the grinder plate since it was difficult to slide the plate in without it tilting. 6) Rifling has been used on the outside because it's easier to clean than knurling and gentler on hands (and sponges); Clarkerubber also featured rifling as one of his options. Another notable feature is the flared holes on the bottom of the grinder plate designed to minimize clogging. UPDATE 2019-06-09 Following user feedback and testing with a common herb found in Colorado, I've added two new grinder plates. The original plate had a 1mm gap between the blades and the plate; this gap has been eliminated in the new plates, one of which features an inverted design with the flared side up. Users can decide for themselves which they prefer. I've also included two additional pieces: a Cap and a Funnel. Both can be screwed to the bottom bowl. The Cap allows users to further mix ground herbs by shaking it or storing them securely. The Funnel makes pouring herb into other containers effortless without spilling a drop. If you've previously printed parts from last week's publication, don't worry – those parts remain unchanged.
