Summary from FirstKlund

This is my take on a WDT Tool for distribution of espresso grounds after grinding. Requires 5 0.4mm stainless steel nozzle cleaning tools. I printed the two parts of the tool together at 0.2 with adaptive layers turned on, and the threads worked perfectly for me.

NOTE 1-25-2022: Added WDT Holder V2. This holder is much improved, and has space in the base for 6 American pennies. Stop the print after the holes are finished, insert pennies, restart print. Much more solid base.

NOTE 2-18-2022: Added WDT Tool New Top - I didn't realize that I had never uploaded the new top that works with the new holder. Either the old Top/Bottom names are wrong, or Thingiverse's thumbnails are wrong. But this new Top works with the older version's Bottom, whatever it's called. You'll know when you put them in your slicer.
