Espresso Distribution Tool

thingiverse

Espresso coffee grounds distribution tool with holder. This tool uses 0.5 mm diameter stainless steel spring wire, which I happened to have on hand from other projects. The tool uses 6 wire tines, cut to a length of 65 mm. To secure the wires in the handle, I just dipped each wire in a bit of 2-part epoxy before inserting. Edit: Because some may think that 0.5 mm wires are larger than ideal, and because acupuncture needles are readily available online, I have added a 2nd handle design intended to accept 0.4 mm acupuncture needles (distrib_tool_handle_04.stl). This design uses 4 needles, arranged similarly to that of the Decent Puck Rake. The needles I used have a ~29 mm long "handle" section which is 1.4 mm diameter, which is the section that is inserted and epoxied into the 3D printed handle. I cut the needles to a total length of about 80 mm overall. When inserted into the handle, this leaves about 50 mm of needle length extending from the handle. It fits into the same base holder as the original handle design.
