An neat-looking, easy-to-print funnel that stays in place with the help of some magnets. This was designed for the 1ZPresso JX Pro, but may work with other 1ZPresso hand grinders with a 62mm outer diameter.
There's space in the bottom of the center cone for 3x 1/4" (Outer diameter) x 1/16" (Height) magnets, but it also works great without them!
Food Safety
Printing a part from food safe plastic does not make it food safe! The surface of FDM 3D prints traps bacteria and is usually not water-tight, even if it looks like it is.
Because the funnel is in regular contact with coffee, consider coating it with an epoxy specifically approved for food contact. The funnel in the pictures was coated with MAX CLR after the photos were taken which is formulated for direct food contact in accordance with FDA regulations. Check out some of my other coffee related items if you want to see what the finish looks like after epoxy is applied. Always follow all manufacturer curing and use guidelines to ensure the finish is food safe. Be sure to wash the part with warm soapy water after the epoxy cures before using.
Printing Recommendations
You will need supports for the lip that rests on the top of the grinder, but the angled gussets should print without supports. In some cases the slicer likes to put the seam on the underside of the gussets, which can cause some weird printing artifacts with PETG. If this bothers you, try printing with random seams, or manually adjusting the seam so it's not on the bottom of the gusset.
