WDT Assembly: Distribution tool (Iris & pupil)

The 1 mm holes are 1 mm in CAD, but appear smaller when printed, you know the deal.. My other needles were too thick, but i'm sure if you torch the tip of regular needles, they will just glide in.

I provided a version with 2 mm holes as well - it's totally up to you printer tolerances..

Needed components:

• 9 needles
  • max. length: 50 mm
  • min. thickness: ca. 0.4 mm
  • max. thickness: ca. 1.8 mm

1. Poke the needles through the holes in the iris
2. Use Play dough, hot glue or other glue to hold the needles in place
3. Close the iris with the pupil
4. Put everything together and get ready for a perfect extraction. Cheers! ;)
