Introduction

This is Yet Another DIY Eductor - aka YADE.

Advantages:

  • the eductor nozzle widens from 3/4" to 1", helping to spread the outgoing flow.
  • ABS free (for people who care about that)

Cut the slots as show. A radial arm saw is ideal, but a hacksaw will work in a pinch.

Final Assembly

Press-fit all 3 components together.

Note that I cut this prototype's slots too high. If you do this, just fill in that area with aquarium silicone.
