Bottle irrigator for plant watering

thingiverse

This is a bottle irrigator to keep a 4-5mm level of water in a planter. I added a ring of 3mm to level up the bottle if the level is to low for the planter.(simply pass the ring on the main cylinder) The main cylinder Ø is 21mm then check the bottleneck of bottle you want to use. IMPORTANT : Use white or transparent filament, don't use dark color or the sun will deform it by the heat and weight of the full bottle. I also added a star shaped part to increase the level of a plant if you want a level of water under the plant but not that the plant has feet in the water
