Build It Yourself: Slow Feeder Pro V1
The Slow Feeder Pro V1 is open-source, and you can build the whole thing yourself.
The 3D-printable files, the full parts list, and the assembly instructions are all free. If you own a 3D printer and don't mind sourcing a few small electronic parts, this is everything you need to build your own slow feeder from scratch.

Don't want to source the parts?
Sourcing a dozen small parts isn't for everyone. If you'd rather get the electronics in one box, matched to your grinder, grab the Slow Feeder Pro V1 kit. You still print the body yourself and follow the same guide.

What is Slow Feeding?
Slow feeding is the practice of introducing coffee beans into the grinder gradually rather than all at once.
By regulating the feed rate, the grinder runs under a lighter, more consistent load, allowing the burrs to cut each bean cleanly instead of crushing or fracturing it under pressure.
Does it actually make coffee taste better?
YES! Slow feeding is widely praised by coffee enthusiasts for producing noticeably cleaner and more consistent brews. Users report fewer fines, improved flavor clarity, less bitterness, and more balanced extraction. Slowing the bean feed reduces grinder overload, minimizes heat build-up, and results in a tighter particle size distribution compared to traditional dumping methods.
