Hario coffee mill powered by a motor

thingiverse

I managed to scrounge up a worm geared motor from some old electronics that are now collecting dust, and after hours of tinkering, I got it working. To turn this quirky contraption into an auto grinder for my Hario coffee mill, simply attach the motor to its place with ease. If you're planning to modify this project to suit your needs, be warned: you'll likely need to fine-tune a few numbers to get it just right, as my printer's accuracy is questionable at best – I've had to redo the coupler a grueling three times! **Getting Started** Start by printing the checkerboard base. Its intricate design ensures accurate dimensioning and will serve as your motor mount once you're ready.
