<p>This thing was crowd designed by the members of the <a href="https://discord.gg/espresso">Espresso Aficianados Discord</a>. If this design or espresso interests you, hop in and say hello!</p> <h3> The Tool</h3> <p>A nine pronged WDT tool. This was designed for 0.4x75mm 0.35x75mm acupuncture needles with a 30mm handle. The total length of the needle is 105mm (see photo). I used <a href="https://www.aliexpress.com/item/1005001467649993.html">https://www.aliexpress.com/item/1005001467649993.html</a>. Others have used 3d printer needles from amazon 1 2.</p> <p>Dull the tips of the needles on an emery board or sandpaper before installing. Store tip down in a cup of rice for safety and to clean the needles.</p> <h3> Printing</h3> <p>Print cap upside down (threads up)</p> <h3> Youtube features:</h3> <ul> <li><a href="https://www.youtube.com/watch?v=YxRgqz-_BYU">Brian Quan</a></li> <li><a href="https://www.youtube.com/watch?v=xp3GIR9lynE">Lance Hedrick</a></li> <li><a href="https://www.youtube.com/watch?v=9ph1_gjvD8s">Hoon's Coffee</a></li> <li><p><a href="https://youtu.be/X3bEjJ_S2V0">James Hoffmann</a></p> <h3>Licensing</h3> <p>A note to commercial printers: this WDT is meant to be affordable and accessible for espresso enthusiasts. I give permission to print and sell these as long as the following conditions are met. 0. Any posting should include a link to this design. 1. Prints should include needles. 2. Total cost may not exceed 9 USD. 3. If a stand is included, total cost should not exceed 10 USD. Total costs exclude shipping and handling.</p> <h3>Edits</h3> <p>Edit 7: Modified licensing terms to exclude shipping and handling cost.</p> <p>Edit 6: Added two piece WDT holder that breaks apart for easier shipping.</p> <p>Edit 5: Modified licensing terms to allow limited commercial printing.</p> <p>Edit 4: In terms of needle diameters, 0.25mm deforms too easily to WDT effectively. 0.3mm is nice if using bottom filters as it causes less disturbance. 0.35mm is nearly as robust as a 0.4mm needle, but moves the coffee less. 0.4mm is the sturdiest of them all but moves the coffee around the most. Any size between 0.3-0.4mm will work, but 0.35mm is a nice compromise.</p> <p>Edit3: Added a bottom with bigger holes (1.2mm rather than 1mm) for the needle for folks having trouble with the hole size.</p> <p>Edit2: By popular demand, i've added a WDT holder base. It comes in a 70mm octagonal base and a 58.5mm circular base (to fit various accessory holders).</p> <p>Edit: added a magnetic clip STL and updated the fusion file to include it. This uses 4 5x1mm magnets (https://www.amazon.com/gp/product/B07JDBLVBZ/ref=ppx\_yo\_dt\_b\_search\_asin\_title?ie=UTF8&amp;psc=1), but 2 5x2mm magnets should fit as well.</p> <h3>Print Settings</h3> </li> </ul> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p><strong>Printer:</strong></p> <p>I3 MK3S</p> <p><strong>Rafts:</strong></p> <p>No</p> <p><strong>Supports:</strong></p> <p>No</p> <p><strong>Resolution:</strong></p> <p>0.15mm z height</p> <p><strong>Infill:</strong></p> <p>15</p> <p><strong>Filament:</strong> Hatchbox PLA Black and Silver<br/> <strong>Notes:</strong></p> <p>Print with threads up</p> Category: Kitchen &amp; Dining
