Turn your IKEA Tertial into a photography light
This simple 3D-printed attachment turns the IKEA Tertial desk lamp into a more controlled directional light source for tabletop, product and close-up photography.
The grid helps control light spill and creates more defined, directional illumination without requiring a dedicated photography light.
Choose your own grid
The grid is not a separate part — it is created using the infill of the model itself.
This means you can customize the attachment directly in your slicer:
Grid infill for a square grid
Honeycomb infill for a hexagonal grid
Choose your preferred infill density
Experiment with other slicer infill patterns
One model can therefore produce many different grid configurations without modifying the STL.
Designed for real photography
I designed and tested the attachment for tabletop photography. In the example shown, it was used to photograph a small miniature, providing controlled directional illumination while keeping the setup compact and inexpensive.
The attachment is designed specifically around the IKEA Tertial lamp and can be installed without modifying the lamp.
Printing
The model is designed to be printed as a single piece.
Print Settings:
Top layers: 0
Bottom Layers: 0
Perimeters: 6 (not less than 3 mm)
Infill: Grid or Honeycomb
Infill density: 15%-25%
The exact infill density can be adjusted according to your needs and printer.
Recommended:
No supports
Use the infill pattern and density that gives the light control you want
Quick DIY diffuser: A thin piece of translucent white plastic can also be used as an additional diffusion layer between the lamp shade and the attachment. I tested this with a cool-running LED bulb. Do not use this with incandescent or halogen bulbs, and make sure the material cannot contact the hot bulb.
Important: Make sure the lamp and bulb remain within their normal operating temperature limits. Do not use materials or printing settings that are unsuitable for the temperature of your particular bulb.
