Grinder Setting Dial for Eureka Mignon | Aluminum Dial Faceplates | Solid Aluminum Grind Adjustment Knob

I saw a video with this addition to somebody's Eureka Mignon grinder and when somebody else asked about it, they linked here. I had to go get one. I've loved my Mignon Facile grinder, but the one frustrating element has been the tiny hard-to-fine-adjust fineness knob. Making a really small nudge can make a noticeable difference in grind, but it can be hard to make such a small adjustment with the small knob. This new knob is larger and also shows the degree of adjustment more clearly and granularly on the much larger included indicator that surrounds the hopper. I've found it far easier now to make exactly the adjustment I need to get from, say, slightly too coarse so that I'm getting a 17 second shot to just right in the 25-35 second range. I can more precisely move it the right degree to get to my desired result. Besides the great increase in functional utility, this mod is solid, made out of a quality painted aluminum that feels nice and will last along with this well-built grinder. It also looks great. The printing on the knob and the large indicator is attractive and clean and easy to read. It makes the grinder look a lot better. I've paired it with a single-dosing bellows attachment that replaces the big bulk hopper and the whole thing looks great. There are replacement knob projects available on the various 3D printing model websites. I've tried two of those and they looked OK, but those tend to slip over the existing knob and require attachment of a separate arrow to point to the coarseness number. I was never able to get the slip-over knob to securely attach -- rather, it would sometimes slip and make adjustment uncertain. Also, the plastic isn't as solid and doesn't look as nice. This alternative aluminum upgrade uses a complete replacement for the knob so it won't slip. It turns the grinder mechanism exactly as the original knob, but with the larger visual and easier control. If you have any of the Eureka Mignon models that are compatible with this upgrade, I highly recommend it.

Very pretty and functional upgrade for my Eureka mignon facile. Gives myself a number for each coffee bean. Also gives the grinder a more premium feel. Install only takes about a minute, but you will have to re calibrate the 0 point on your grinder whenever you clean your grinder now. Also, you’ll have to dial in your beans when you first install this. Nate answers all questions right away. For that, and the high quality, I will give it a 5. In regards to the aluminum. I don’t doubt it is aluminum, but it feels like the faceplate is plastic. So I wouldn’t buy this solely to get an “aluminum look” to match the aluminum body of your grinder. That said; the lazer engraved numbers are likely higher precision and class than the competitors, and the dial itself is certainly aluminum. I like it and am having fun playing with the settings.

This is just a perfectly designed piece of gear. Fits perfectly - nothing to glue on or change; made of high-quality materials (metal knob), and most importantly, makes dialing in a shot with this grinder much much easier. Was about to return my grinder out of frustration but glad that I kept it. On top of that, ARO has made a very easy to follow instructional video that you simply watch (no wasted paper instructions).

A much needed upgrade for the Eureka Mignon. Dont be worried about build quality, this is a really nice item.

Which is your ability to measure and replicate a grind setting. This mod is tight fitting, and has a nice metal knob. It does enable repeatable grinds. I’m able to go to 20 (quite fine) for one of my espresso blends, and then 70 for a reverse brewer I have, then back to 20 and still get a 27ish second extraction on my gaggia classic pro espresso machine. This showcases the use-case for this mod; if you switch grind settings often and need to be able to go back. This does not come without some minor flaws though. While the knob and dial plate is metal, the dial housing is plastic and the dial gear/base (not viable) is obviously 3D printed. I think the cost of this mod is a bit too expensive. Regardless, it still may be worth the added functionality. This mod kit pays for itself by saving me beans from dialing in. Is it worth it for you?

This dial is miles beyond the awful, practically-useless ones sold with the Mignon line. It takes all of a minute to install and is worth every penny.

Installed on Eureka Specialita. Easy to install. Seems well made. This makes adjusting grind size much easier and more accurate than standard design. Recommend this if you want to get the most out of a Eureka grinder.

Included knob dimensions do not work with Specialita. Due to the shorter height, when it is installed and turned for a finer grind, it hits the grind size indicator bump on the top of the grinder's face plate. See photos. Very disappointed. As others have reported, this item is advertised as being aluminum. However, it is mostly 3D printed plastic, with some thin aluminum overlays.

Prima oplossing, wat een verademing om zo precies je maalgraad te kunnen instellen. Zeer makkelijke installatie en kwalitatief goed materiaal. Tikkeltje prijzig maar het wel waard vind ik.

Great upgrade to my grinder

Das Mahlwerk-Einstellrad von ARO ist ehrlich in folgenden Punkten sehr gut: Design, Verarbeitung, Handhabung und Lesbarkeit, Passgenauigkei. Die Montage ist wirklich einfach und in einem Video sehr gut veranschaulicht. Das ARO passt auf meine neue Mignon Einzel-Shot super. Die Zahlenscheibe wackelt nicht , lässt sich auch gut wieder abnehmen. Ich kann das ARO wirklich empfehlen und es ist ein muss wenn mann gerne mal die Bohnen wechselt. Sehr gute Zahlen / Stricheinteilung auf der Skala.

A little expensive for what it is, but it's very well made so I can't complain too much. The dials that ship with most of the Mignon grinders are very difficult to use, especially in small increments. This completely fixes that problem and looks great on the grinder. It fits like it's a factory-made accessory.
