I really loved the Dosing Cup Holder by tarik (Marked as a remix here) but I had a Eureka Silenzio, which doesn't come with the adjustable fork part needed for it. I designed my own to the best of my ability to match what I believe the original was (Based on the fixed fork that came with my grinder and pictures)
Since this is made of plastic, it doesn't mount as well as the original metal kit, so it jiggles a little, but it can be modified to be thicker or include a magnet to hold better.

After using a few times, I noticed the dosing cup wasn't as high as I wanted it to be. You can use a longer M3 screw in order to pitch it up, but it scratches the front of the grinder if you do so without protecting it. In the end, I cut a small piece of foam to protect it, and screwed the bolt into it. Now it's sturdy and doesn't rock around.
Note that there is a remix of this model by madmax that seems to fix this issue. Print his before mine!
The author remixed this model.
Not really so much of a remix as much as an accommodation.
