thingiverse

A nine pronged WDT tool that's printable in a business card size. This was designed for 0.35x75mm acupuncture needles with a 30mm handle. I used https://www.aliexpress.com/item/1005001467649993.html. Dull the tips of the needles on an emery board or sandpaper before installing. Store tip down in a cup of rice for safety and to clean the needles. For assembly, I highly recommend watching the instructions in the accompanying [youtube video](https://youtu.be/R5fCZbRs1vE?t=337). Instructions are also available in a [google doc](https://docs.google.com/document/d/13WSx_Eza2ZAv9LtDTPxjcbTFiYmyUyMLKeBUElrQMHA/edit?usp=sharing).
