Give your empty plastic bottles a second life! This clever, simple attachment instantly transforms any standard beverage bottle into a fully functional watering can. Perfect for indoor houseplants, balcony gardens, or delicately watering fragile seedlings without washing away the soil.

🌟 Key Features

  • Universal Fit: Designed to seamlessly screw onto standard PET plastic bottles.
  • Gentle Shower Effect: The precision-placed holes create a soft, evenly distributed flow of water, preventing soil disruption and protecting delicate leaves.
  • Ultimate Upcycling: Reduce plastic waste by repurposing single-use bottles into a durable, everyday gardening tool.
  • Compact & Portable: Why buy a bulky watering can when you can just print this tiny cap and use a bottle you already have? Perfect for small apartments with limited storage space.

🖨️ Recommended Print Settings

  • Material: PETG is highly recommended due to its excellent layer adhesion and water resistance. PLA will also work perfectly fine for indoor use, but avoid leaving it in direct, hot sunlight.
  • Layer Height: 0.16mm or 0.2mm. A slightly lower layer height helps the internal screw threads print cleanly and ensures a watertight seal.
  • Perimeters (Walls): Use at least 3 to 4 perimeters to guarantee the walls are watertight and can handle the water pressure when you squeeze the bottle.
  • Infill: 15-20% is sufficient, as the model relies mostly on its solid walls.
  • Orientation & Supports: Print the cap face-down (with the flat side containing the holes resting directly on the build plate). No supports are required!
