Description
Cylindrical LED Lamp 12V – G4 Socket – Modular Design – M2 Brass Inserts – No Glue
Cylindrical 3D Printed lamp with G4 socket, brass threaded inserts, and fully mechanical assembly.
Project designed to be printed, assembled, and used without modifications.
The objective is not aesthetic but functional:
👉 to transform standard components into a real, replicable, and maintainable lamp
Main features:
- modular 3D printed structure
- upper diffuser for soft light
- standard G4 LED socket
- DC power via jack
- integrated switch
- glue-free assembly
Distinguishing feature of the project:
👉 use of Rutex M2 brass threaded inserts
→ ensure strong and reusable threads over time

- Upper diffuser
- Lamp holder support
- Bottom base
- Insert Rutex M2 inserts hot
- Mount lamp holder in support
- Connect G4 LED
- Wire DC jack and switch
- Insert everything into the body
- Close with M2 screws
🧠 🟥 TECHNICAL NOTES (REAL VALUE)
- Rutex inserts drastically improve product durability
- The G4 LED generates heat → avoid PLA in enclosed spaces
- The 3S battery can reach 12.6V → pay attention to LED compatibility
- Light diffusion depends on the diffuser material
