This is a custom 3-module 3D printed lamp designed to be simple, clean and fully modular. The model is made from three separate parts: the bottom base, the translucent spiral diffuser/shade, and the top cap. Everything fits together easily after printing, without any complicated assembly.

The base and top cap were printed from SUNLU Matte PLA+ 2.0, while the middle diffuser was printed from SUNLU Transparent PLA+ 2.0. The diffuser is designed to work especially well in vase / spiral mode, creating a thin translucent wall that spreads the light nicely through the spiral texture.

I plan to add more top-section variations and modifications over time, especially if people like the model and share their prints. The idea is to keep the lamp modular, so different tops, shades or design styles can be swapped in later.

Print Settings I Used
Base and top cap:
Printed normally as simple solid parts.

Middle diffuser / shade:
Printed in Vase Mode / Spiral Mode
1 perimeter
No top layers
No bottom layers
No support
No brim
No glue needed on my Creality K2

The diffuser is basically a clean translucent spiral cylinder, so vase mode works very well for it.

Important Safety Warning
Use only a cold light source that does not generate heat. PLA is not heat resistant and can deform if exposed to high temperatures.

Do not use candles, halogen bulbs, incandescent bulbs, or any hot light source. I strongly recommend using only a low-heat LED module or similar cool light source. Always test the temperature before leaving the lamp running for a longer time.

This is the type of light source I used, mainly so you can check the dimensions:

Materials Used
SUNLU Matte PLA+ 2.0 for the base and top
SUNLU Transparent PLA+ 2.0 for the diffuser/shade

Notes
The lamp is designed as a decorative ambient light. The translucent spiral shade gives the light a soft and interesting texture, while the matte black top and base keep the design minimal and modern.

If you print it, feel free to share your result. I would love to see different color combinations and setups.
