PET Bottle Foam Gun for Garden hose. Constant Soap dispenser.

You will need a type of valve on the hose, like i have in picture.

Model need 1 o-ring on gardena plug and 1 big o-ring inside nozzle or else user WILL be wet. 
I use o-rings but designet a TPU seal too. 
I have testet TPU seal and it works, but should be glued in so it never falls off.

Mini version. 3.5mm SoapHole.  Original is 2mm.

Mini  version drains 0.5l bottle in 20sec without nozzle.

Mini  version drains 0.5l bottle in 40 sec with ‘slitt Nozzle’.

Mini  version drains 0.5l bottle in 50sec with ‘multible holes nozzle’. 

Need 9mm tube down in bottle to work.       (9mm Inside tube)

Link for the valve for ¾ Thread Model, still have to turn off water when change back to clean water but makes it operate able.

May have to use some sandpaper if gardena coupling doesn't fit, should be tight fit. 

Need support only on build plate and only for gardena plug, normal support is better than tree support on this.

I printed with PETG and 0.6 mm nozzle. (3.5hour)
initial layer height - 0,2mm
layer height 0.2

3 Walls.
7 Bottom & 7 Top.
20% Gyroid infill.
Normal Support only for gardena plug.

This will deliver constant soap until bottle is empty.
I adjusted the inside 2mm tube's angle so it will drain the bottle when water flowing trough.
Prints flat.
Also added 1 air hole so bottle dont get vakuumed flat. Bottle will not need hole.
No Glue needed.
