Update 2025-08-06
New print profile with smoother threads added. The thread design has been refined, and the profile has been tuned specifically to improve thread quality. Yes, this is a second “smoother” profile. Test both and see whitch one works best for you.

Update 2025-06-23
New print profile with smoother threads added. The thread design has been refined, and the profile has been tuned specifically to improve thread quality.

A set of three 3D-printed parts for a micro irrigation system using 6/4 mm tubing (6 mm outer diameter, 4 mm inner diameter):

1. Adjustable Valve:
A short tube with a hose connector on one end and internal threads. A longitudinal slot on the side of the tube lets water out. A screw is inserted at the end of the tube to adjust the water flow. When fully tightened, the valve is sealed. As the screw is unscrewed, more of the slot opens and increases the flow. Designed to solve the problem with many kits where either the nozzles are non-adjustable or adjust poorly and inconsistently.
When fully tightened, the valve should stop the flow completely, but whether it does so entirely depends on the print quality and the water pressure. Most likely, the flow will not stop completely.

2. Extension:
A simple connector with hose fittings on both ends, used to connect two tubes.

3. End Stop (Cap):
A small round plug with a hose connector, used to seal the end of a tube.

Printing Tips:
The threads are sensitive to print quality and work best when printed in PLA.
The extension should be printed with a brim for better bed adhesion (the printprofile is already prepared for this).
The valve body may also require a brim depending on your printer's first layer adhesion. The other parts generally print fine without brim.

One of these is solid in the center I don't understand why but I guess it's supposed to be like that but it works well

@JesperEkvall

It is intended for use as a plug at the end of a hose It is not strictly necessary, but I use it when shortening a longer line with multiple valves Thank you for your feedback

@JesperEkvall

It functions as a plug if you want to seal the end of a hose. I use it when splitting a longer hose with T-connectors. Then I have ready-made "plugs" with a short hose piece attached that I put on the last T-connector

Replying to @JesperEkvall :

Okay, I understand :)

@Daddy2

ok, maybe I’m dumb… I can’t figure out how to assemble them… any instructions so I can give it a review? I’m trying to build another grow rack for fodder and I need these up and going ASAP…

The designer has replied

@JesperEkvall

Thanks for your comment! Have you printed the full plate? If so there are only two of the four pieces that can be assembled together. The "screw" fits in the "house". The "house" has a threaded inside. What material do you print it in (PLA, PETG...)? Only use PLA!

@Daddy2

I’m using pla I printed a partial the first time then I printed the full rack. still can’t figure it out. I mean maybe I’m over complicating it does the water only come put of the little slot on the side? I need more of a spray then anything if so I dont think thill work for me.

@JesperEkvall

It's not going to spray. This is meant to be used for low-pressure watering. I'll review my description to see if it needs an update.

After several attempts on various printers without success No idea what the issue is

@JesperEkvall

Ok, please add a little more info and we will sort it out. What is the result of the print? Only one piece printed at a time or multiple? All different pieces printed at a time? One of the pieces not printable? All pieces not printable? Lack of adhesion (parts breaks loose)? Add a picture if possible. Filament (use only PLA as recommended in description) used?

@JesperEkvall

Whats happening! Please attach a picture if possible.

@JesperEkvall

Please give a little bit more information about what was not going well!

@silentdrummer

can you please provide a PETG model? PLA is not UV resistant and probably needs to be re-printed every year. thanks

The designer has replied

@JesperEkvall

Threads at this size are quite challenging to get right, even in PLA. Printing the design in PETG would be a whole different level of difficulty. PETG generally has slightly lower dimensional accuracy and looser tolerances than PLA, which would make it even harder to achieve a good result. Unfortunately, it's not something I'm going to take on. I hope you can understand, and I appreciate your understanding.

@MatejB

Doesn't work for me. Printed with smoother threads profile. It doesn't provide waterproof sealing, so it is impossible to preciselly controll drops. It is good only if you need to reduce flow from connected hose.

@user_1706657589

how many liters per hour flow out of there

The designer has replied

@JesperEkvall

Thanks for your comment! I don’t know — it also depends on the water pressure you have and how much pressure the nozzles can handle before they come loose from the hose. I could test it, but I have no way of measuring the water pressure, so the information would be partly irrelevant. The simplest thing is for you to try it.

Sorry, but have printe these with 2 different nozzles only to find they still drip (loads) even when screwed all the way in. Good idea, but does not work.
