It’s safe to say that a Venn diagram of Hackaday readers and coffee drinkers would have significant intersection, many of you will be lovers of the bean. Some of you will be happy enough with a spoonful of instant granules and a bit of boiling water, but among your number there will undoubtedly be owners of significant quantities of coffee-related machinery and paraphernalia.

If your coffee enthusiasm extends to grinding your own direct from the bean, then [Christian Pederkoff]’s project should hit the mark, he’s created a rather neat 3D-printed coffee grinder. Sadly the creation of a steel burr and ring was beyond his 3D-printing capabilities so those parts come from a commercial grinder, but the housing, shaft coupler and hopper are all from his printer. Power is from a conveniently available source, he’s made use of an automotive windscreen wiper motor. The whole is a straightforward and easy-to-assemble unit that we think would sit well alongside many readers’ coffee making equipment.

If coffee projects are your thing, we have a few for your entertainment. Another not quite so neat enclosure for a coffee grinder, for example, or a tea-light-powered filter coffee machine for power cut beverage satisfaction.
