Rancilio Rocky alternate doser

prusaprinters

<p>The Rancilio Rocky is a very popular coffee grinder but the doser is terrible. This is a doser that delivers a single shot cleanly into the portafilter.</p> <h3>Instructions</h3> <p>The photograph shows the Rancilio doser model for which this replacement is intended. The STL's will provide a new doser bowl and plunger and lid. Once printed the bowl is easily attached with the existing Rancilio hardware fittings; firm as a rock (!).</p> <p>You can find a video of it at work at <a href="http://youtu.be/0S_ugKZQhtQ">http://youtu.be/0S_ugKZQhtQ</a>. For those interested in the timer underneath the grinder, the PDF file includes the circuit schematic and sourcing details.</p> <p>UPDATE 2013.04</p> <p>There are now STL's for dual color printing so you can have a different colored "tell" on the chute. If you have printed the main part in black, it can be very difficult to see whether you already have a dose ground in the hopper. There is now an inset that you can print in another color - I use white - which makes it less likely you will "double grind" by mistake. The wide base flange you just cut off with scissors; stops all warping!</p> <p>UPDATE 2021</p> <p>Added complete 3DM as well as bowl OBJ and 3MF files so you can edit your own portafilter sizes...</p> Category: Kitchen & Dining
