Modular L & T Solar Lamp – Scalable Outdoor Light

Boost MeIf you like modular designs that do something, give this project a boost. These solar lamps grow with your needs – literally. Adjustable height, clean geometry, fast printing. Support means more builds coming your way – thanks!

This modular solar lamp system combines classic outdoor lighting shapes with a scalable, user-configurable structure. The L-shaped version provides direct downlighting with one module, while the T-shaped variant holds two solar LED modules for wider coverage.
The key feature: the vertical section is modular and stackable – adjust the height as needed using repeatable middle segments.

• Designed for 10 cm solar LED modules with daylight sensor and 15 lm warm white LEDs
• Powered by 3.7 V / 1200 mAh batteries per module
• Fully modular: vertical segments can be stacked to any height
• Clean design, no support needed
• Prints with 10 % infill by default – more for higher durability
• Can be glued together for extra strength
• Base can be mounted with ground spike
