Sunsun HW-303b Eductor

thingiverse

This is a slight remix of the "Aquarium Flow (1/2in Loc-Line 55% scale for 1/4, 132-131% for 3/4)" by Cleven to fit the standard output of the Sunsun HW-303b and probably the HW-302 also. The designer did a very nice job and it works well on my HW-303b. It churns the water into a vortex and gets good movement going. Print it in the position it is in the file and it doesn't need supports. I printed in clear PLA to be sure it was aquarium safe. Printed at .2 and how ever much infill you like, I'd also recommend using a brim otherwise there isn't very much in contact with the build plate.
