Plant irrigation spike

pinshape

For plants to stay hydrated indoors or out, use this supplement to regular watering. It can also serve as a primary source when water is not possible, such as during a vacation. After numerous design modifications, I chose this one, which, based on my tests, should last almost a week - depending on how your 3D printer handles the tip of the lower section. The included .stl file has a small hole at the tip, but it didn't print on my machine. This may explain why the "irrigation" lasted nearly a week. However, this issue can be easily resolved by lightly cutting off the tip with an X-ACTO knife. In my opinion, it's better for it to last longer than shorter, but not too long! All other side holes printed correctly. Please use ABS filament; I'm unsure if PLA or other materials will work properly. My experience has shown that ABS works well with water - it doesn't leak or disintegrate over time. Print the two parts upright and then assemble them together. Note that they fit tightly, by design, to prevent leakage. They are designed to fit most plastic 16.9 oz (500 mL) water bottles and even 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
