I was looking for a WDT tool for a reasonable cost and came across Prong Espresso Distribution Tool WDT by jkim_makes. I had four extra made to share some of the cost/faff of ordering prints and avoid having 90 unused acupuncture needles sat in a drawer.

The £10 includes:
WDT tool
Base (2part screw version)
20 x 0.35mm acupuncture needles
£1 tip to the designer on Thingiverse
UK postage

N.B. The needles will come in their protective packaging so you will need to put these in yourself (only takes minute). I would recommend dulling them or using some cutters to chop off the sharp end.
