Passive self-watering 3D-printable floating vegetable pot, inspired by the chinampa (floating garden bed).
The models have been successfully printed in Natural PLA on a Prusa Mk3S+ using a 0.4mm nozzle with an upgraded part cooling duct (See https://www.printables.com/model/906613-highv-part-cooling-duct-for-prusa-i3-mk3s)
NOTE: The standard brass nozzle is not considered food-safe, as it wears out. A stainless-steel or titanium nozzle is recommended if you are even considering printing with food in mind.1
The models have been successfully printed using the following profile with "vase mode" enabled. Note that the profile is for a 0.8 mm nozzle, but have been physically tested on a 0.4 mm nozzle.

Bottom fill pattern: Concentric
Infill speed: 5 mm/s
Solid infill speed: 5 mm/s
Top solid infill speed: 5 mm/s
First layer speed: 5 mm/s
Max print speed: 30 mm/s
Overhang speed:
0% overlap(bridge): 15 mm/s
25% overlap: 1 mm/s
50% overlap: 1 mm/s
75% overlap: 2 mm/s
Extrusion multiplier: 1.2
Nozzle temperature:
First layer: 230 C
Other layers: 230 C
Bed temperature:
First layer: 60 C
Other layers: 60 C
Fan speed:
Min: 100%
Max: 100%
Lift height: 0.8 mm
