This bypass system allows you to use the built-in grinder of your Oracle or Oracle Touch. The portafilter holder is crafted to accommodate a bottomless 58mm portafilter while still activating the internal portafilter switch, ensuring the grinder's functionality. The primary goal is to enable the use of a dosing funnel to contain the grinds within the portafilter, facilitating the use of a WDT tool to reduce channeling through the coffee puck.

While it's possible to use a standard spouted portafilter, the fit may be snug around the lobes, so consider modifying the design for a better fit with the stock portafilter. Alternatively, your own funnel may work if it's sufficiently compact. The impeller is an optional component, yet it's found to enhance grind distribution more effectively than the standard tamp fan or without it.

2 plates - one has the funnel without magnets; the other has holes to suit a 3mm magnet.
