Plant irrigation spike

thingiverse

To keep indoor or outdoor plants hydrated, use this watering system as a supplement to regular watering. It can also be used as the primary source of water when regular watering is not possible, such as during a vacation. After many design changes, I selected this version, which lasted nearly a week in my tests - depending on how your 3D printer prints the tip of the lower section. The .stl file includes a small hole at the tip, but my machine did not print it. This might explain why the "irrigation" lasted almost a week. However, this can be easily fixed by carefully cutting off the tip with an X-ACTO knife. In my opinion, it's better for the irrigation to last longer than shorter, but not too long of course! The other side holes printed fine. Use ABS filament when printing this model - I don't think PLA or other filaments will work properly. My experience has shown that ABS works well with water, does not leak, and does not disintegrate over time. Print the two parts standing upright, then assemble them together. Note that it's a tight fit, which is by design to prevent leakage. This watering system fits most plastic 16.9 oz (500 mL) water bottles, as well as larger ones such as 33.8 oz (1L), as shown in the pictures. Settings: * Layer thickness: .2 micron * Infill percentage: 35% * Perimeter shells: 2 * Top and bottom layers: 3
