4mm Sprinkler System

prusaprinters

I needed to replace the sprayer type sprinklers in my environmental septic system. The Kikuyu grass grows tall and it is hard to see the location of the tiny sprayers. I designed a T connector that presses into a piece of 19mm poly pipe, used as a riser. Printed in orange prusament it is easy to see in the long grass. I also designed a variable dripper type sprinkler with a spike. Its design is based on looking at an existing sprinkler I have, but can't find in the shops anymore. These are also printed in orange for visibility but I have a lot printed in black PETG.  These are in use in the vegetable garden and have been working great. I have included this file as well. There is also a bottom connector that clips to the supply pipe (25mm poly). It supports the 19mm riser and the 4mm pipe connection.I experimented with thinner 4mm connectors but have gone back to thicker ones. You just need to soften the 4mm pipe with hot water when attaching. It makes a much stronger connection.I print the drippers at 0.15mm quality and the rest at 0.2mm speed. I designed it all so no supports are needed, the picture of the parts on the bed show the orientation I use to print. I have been printing the bottom connector and dripper spike with a brim lately as I have had a couple detach mid print.
