This is a single dosing hopper designed specifically for the 804 series of grinders from Ditting. It can be used as is, or with the bellows from the DF64 grinder, available from multiple online retailers.
The hopper is fixed to the grinder's upper burr carrier in the same fashion as the original bulk hopper, and you can use the fixing disc from your factory hopper, but you will need new screws.
The screws I used are specifically designed for plastic. and are 4-20 x 5/8 to secure the funnel ring to the base, and 6-19 x ½ to secure the disc to the base. These screws are available from Amazon with links provided below.
I printed this hopper bot upside down and right side up. Both orientations work, but if doing it right side up, it will take considerably longer, and will require supports.
