I opened the parcel with the conical burrs I've ordered last thursday afternoon (7 pm) and after a few seconds thinking I decided to make the most basic design ever in the shortest amount of time.
Motor is a DC12V with 296rpm output, and burrs are the cheapest I found for about $7. Maximum $50 cost with filament and hardware.
It can do fine grind.
Since the motor only likes to grind when battery is fully charged. I have ordered another motor with even lower output at 161rpm. Then I can with no issues grind beans with the battery on storage charge (11.1V)
A reel can be found if you look for it

Very cool, great project.
How do you adjust the setting for grind size?
Did you look into motors that use mains power? Or was the idea portability, therefore no mains to plug into?

That’s so cool. I’ve entertained the idea of building one from scratch but I was afraid I would struggle with burrs alignment. How’s that going for you? How do you enforce alignment?
Very neat. Excited to see how this progresses. Open source, DIY coffee grinders is such a fantastic idea being that big coffee grinder has such a capitalist mindset.
That’s a great project!
I’ve always wanted to get some fancy burrs and make one myself but I know nothing about the design that is involved.
You’ve piqued my interest! Will you be uploading the STLs?
Is it food safe printing material?
Do you have sample of it? btw its really perfect
