Smart RGB Planter (15x15) – Modular & Customizable

Hi everyone! I’m sharing my 15x15x15 cm planter project. I wanted something clean that looks great on a desk, with a nice light touch for the vibe.

⚙ How it works

The design is modular with slots for 6x3 mm neodymium magnets between the parts. The best part? If you don't want to mess with LEDs and electronics, you can just skip the bottom base and use the pot as is. It still looks super clean and the magnets keep everything perfectly in place.

🛠 The Parts

• Base (Bac dessous): For the RGB version. Fits an ESP8266, a battery, a USB-C charging module, and a power switch.

• Main Body (Bac extérieur): The structure with a dedicated groove at the top to slide your LED strip in.

• Inner Pot (Bac intérieur): Where the soil goes.

  • ⚠ PRO TIP: Print this one with 100% infill. This is crucial to ensure it’s watertight so you don't fry the electronics underneath when watering your plant!

• Diffuser: Print this in white or transparent filament for a smooth light glow.

🔌 Parts List 

If you want to go for the full glowing version, here’s what I used:

• ESP8266 (NodeMCU or Wemos)   or ESP32 

• The Light: WS2812B LED Strip

• Power: 3.7V Li-Po Battery

• Charging: USB-C TP4056 Module

• Switch: Small ON/OFF Button

• Magnets: 6x3 mm Neodymium Magnets
