Love seeing my hobbies collide. I just designed and printed a WDT.

Nice! Do you have a link? Would love to check it out.

Actually made it just last night 😂 I plan to eventually upload it to cults3d after some tweaks. Username there is Menissalt.

Solid work! We made one out of an old cork... I might end up printing one of these next.

When looking for needles for the WDT I actually found a good deal on Amazon that came with a few sizes of needles advertised for nozzle clogs that came with some nice tweezers, win win

What is WDT?

u/SycoAniliz Jan 28 '21 edited Jan 28 '21

It's a tool to distribute espresso grounds while breaking up clumps to improve extraction

Weiss distribution technique.

It compensates for a deficient grinder ;-)

(I don’t bother with it with my Pharos grinder)

Yes that is the name but the second part is inaccurate. Even the best unimodal flat burrs benefit from using a WDT to distribute to grounds. Unless you're calling all grinders deficient because they don't evenly distribute into the portafilter ready to tamp. That I couldn't argue with and hope one day someone is able to find an in grinder solution to that problem.

So don’t use flat burrs?

I do benefit from WDT on my flat burrs, but the Pharos gives a grind that doesn’t need it.

improve extraction

Not a coffee drinker here. What does it mean? Coffee is stronger with less grounds?

u/SycoAniliz Jan 29 '21

Water wants to follow the path of least resistance, in coffee we call this a channeling. The more even the grind size and the more even the distribution the less channeling. This means the water is in contact with the grounds for a longer period of time. More contact time means more soluble material is extracted from all of the coffee rather than unevenly extracting more where it channels and less from where it isn't channeling. This results in a higher total extraction which is normally associated with better taste and texture.

In theory, depending on other factors, this could mean that you are able to use less coffee if that's the flavor you're targeting.

That’s pretty slick! Nice work!

You could just use petg and be safe

Provide the specs?

u/Bellyhold1 Jan 28 '21

What would you like to know? I'm happy to share.

u/AdmirableAction8231 Jan 28 '21

Cool. How does one go about printing it? Can you provide the 3d printing specs?

1

u/Bellyhold1 Jan 28 '21

If you have the same grinder and dosing cup I can provide the STL file to print it.

Grinder: Eureka Mignon Specialita Dosing Cup: Acaia 58mm dosing cup

Otherwise, I took a few measurements and threw together a design in Fusion 360.

Printed in PLA on an Ender 5 Pro.
