Coffee Dosing Funnel, Remixed for KINGrinder P1

March 28, 2025
Description
This dosing funnel remix is designed for the KINGrinder P1 hand grinder, with an inner diameter of 46 mm (this size may work for other similar grinders). To better fit in the grinder body, the funnel base has been extended. I added two spots for slip fit 6x2mm magnets for easy storage on vertical metallic surfaces.
*I've added a v2 funnel, which removes the magnets in favor of a longer stepped base which is a bit more stable in the P1 grinder (which has a non-uniform ID). This prints best funnel side down with small supports.
PLA prints fine with 0.2mm layers and 20% adaptive cubic infill, but I suggest adding supports as the base of this model (versus the original) has more overhang with the magnet design.
For assembly simply put the slider on the funnel. Finish by press fitting the knob on the funnel, though glue is likely required.
