🧾 Description

Thank you all for your interest in my model. This model was created based on my previous experience, as well as your requests and expectations expressed in comments on my previous models. The model utilizes controlled gravity flow with the option of adding a filter element to further reduce the flow depending on demand. The design consists of a spherical reservoir and a screw-on dosing tube. At the bottom of the sphere is a hole that dispenses the appropriate amount of water to the plant. Each sphere can be printed with one of three hole diameters: 0.4 mm, 0.6 mm, and 0.8 mm. 

Note: 

Printing with a 0.4 mm diameter may require retouching the hole after printing, for example, with a pin or needle, as from what I've noticed, the printer doesn't always handle such a small hole. 

However, this isn't a problem, as the holes are conical and require only a thin layer of adjustment at the end of the hole. Additionally, the flow can be regulated by using absorbent material (e.g., cotton wool) placed inside the tube. Less material, greater flow. More material, the flow will decrease.

🪴 Benefits of Using Self-Watering Globes

Self-watering globes are a simple and effective solution that supports everyday plant care. They provide multiple practical advantages for both plants and users.

🌿 Optimal Plant Hydration

Watering globes deliver water gradually and in a controlled manner. This helps plants receive the right amount of moisture while reducing the risk of:

• overwatering
• underwatering
• root rot

⏳ Time Saving

Once filled, the globe can water a plant for several days or even weeks (depending on size and conditions).

➡️ Perfect for busy people or during travel.

🌱 Healthier Plant Growth

Consistent moisture levels promote:

• better growth
• stable root development
• reduced water stress

🎯 Precise Water Control

In adjustable models (e.g., using filtering material):

• water flow can be tailored to specific plant needs
• suitable for both moisture-loving and drought-tolerant plants

🧩 Versatility

Watering globes are suitable for:

• houseplants
• herbs
• small indoor gardens
• greenhouses and balconies

💧 Efficient Water Usage

Slow water release:

• reduces evaporation
• delivers water directly to the root zone
• minimizes water waste

🧼 Ease of Use

• simple operation (fill and insert into soil)
• no installation required
• easy to clean and reuse

🎨 Aesthetic Value

Modern watering globes can also serve as decorative elements:

• enhance the look of plant pots
• complement interior design

📏 Size Variants

Available in three sizes for different plant pots:

💧 Flow System

The model uses a controlled gravity-fed flow system with filtering media

• condensation chamber
• micro flow channels
• optional absorbent medium

How it works:

1. Water flows down via gravity
2. Flow is restricted by channels and filtering material
3. Water is slowly released into soil

🔧 Flow Adjustment

• more cotton → slower flow
• less cotton → faster
• none → fast discharge

🧱 Construction

• spherical reservoir
• threaded sphere-to-tube connection
• dispensing tube
• internal micro-channel system

🖨️ 3D Printing

Material: PLA, PETG (recommended)

Layer height: 0.12–0.16 mm

Walls: 3–4

🌱 Applications

• houseplants
• herbs
• small irrigation systems
