Kitchenaid Mazzer mod

thingiverse

This thing is sort of a work in progress, as I've been adjusting files here and there after printing the parts and improving upon the design. I wanted to upgrade my Kitchenaid Proline Burr grinder, but like many, couldn't get ahold of Ben Choong's mod kit. I eventually stumbled upon janrm's 3d files. Since janrm didn't have a a drill template like Ben's mod, I made one using janrm's files. Since it's probably not a great idea to use plastic for the back burr adapter like the aluminum one Ben uses, I decided to drill directly into the body of the grinder and use a plastic adapter that doesn't require heavy structural integrity. Also, I found I needed an adapter despite reading in forums that other people just attached the burr directly to the body of the grinder. The mazzer burrs are at least a millimeter larger in diameter compared to the stock burrs. They won’t fit into the little round cavity that’s in the back of the grinder. I've edited the adapter plate so there's a hole at the top. The grinder seems to work better with all screws screwed in. Since the third hole isn't aligned with a hole in the body of the grinder, fix the screw with a nut on the other end. Then attach the burr with the adapter to the body of the grinder. I think the mazzer mini burrs use m5 machine screws. I couldn't find any that fit the burr nicely at my local hardware stores, so I used 8-32 screws. I think 8-32 is a bit smaller than m5, but the drill templates should work for either. If you print in plastic, you can just drill right through it easily. Also, this mod creates a lot of grind retention in the grinder. More so than using the stock burrs. So I made some washers that fit behind the stationary back burr. I made a 2 mm thick washer, and a 1 mm thick washer. Depending on how fine you plan to grind, you can use one or the other, or stack them and use both. I suggest watching Ben Choong's video before attempting this mod. It really helped me out on what parts were needed. Lastly, try to print these files in white, so that if any of the parts start breaking apart, you can more easily see it in the grinds. The only part I would not print in white is the adjuster spacer, I would print that in black to preserve the aesthetic of the grinder.
