Pop bottle watering cap

thingiverse

When you are starting seedlings, you want a very fine water stream so you don't disturb the soil and expose the seeds. This attaches to the top of a pop bottle. Not all the weeping holes get allow water to pass, but enough do that it works fine. Print Settings Printer Brand: Prusa Printer: Prusa Steel Rafts: No Supports: No Resolution: 0.2mm layer height, 0.4mm nozzel Infill: 30% Notes: Printed in PLA but any plastic should do. How I Designed This I used a third party library to implement the threads. It's included at the top of the scad file. Multiple interations until main hole was large enough to fit the pop bottle and the weeping holes actually passed water.
