Adjustable coffee distribution tool

thingiverse

If you're stumped on how to place multiple needles in your WDT tool, take a deep breath and remember that for optimal coffee distribution, one needle is all you need. Next, try printing this design and experimenting with different placement patterns to get the hang of it. I've used needles from a well-known Chinese online marketplace for cleaning 3D printer nozzles - although I haven't tried them for this purpose before. You might also find them marketed as acupuncture needles. The needle length is a sturdy 75mm.
