The author developed a method for creating 3D-printed lamps using local AI instead of paid online services. The process utilizes the TRELLIS.2 model, which runs locally on a PC with an RTX 5060 Ti 16 GB graphics card, allowing for unlimited model generation.
For complex shapes like an orc skull, the author used TRELLIS.2 to generate a base mesh, followed by Python scripts to create a cavity for the light and add structural supports. The process involved fixing mesh errors, such as incorrect base alignment and internal ceiling geometry, to ensure printability.
The planet-shaped lamp is a lithophane, where light intensity is controlled by varying the plastic thickness between 0.8 mm and 3.0 mm. The author used Python scripts to map a 2:1 image projection onto a sphere, ensuring the design fits a standard E27 lamp holder.
To create a custom stand, the author used the FLUX.1 Krea dev model via ComfyUI to generate sketches, which were then converted to 3D volumes by TRELLIS.2. The geometry was further processed with Python, NumPy, and manifold3d to ensure the lamp could be installed without interference.
All scripts, instructions, and sample STL files are available on GitHub. The author emphasizes that while AI is effective for creative shapes, mechanical components and assembly paths require precise manual calculation and verification within a slicer software.
