Pixel Knock Grid Generator
Upload an image and generate a 3D printable pixel grid STL for pixel craft blocks. All processing runs locally in your browser.
Pixel Knock Grid Generator
Turn an image into a 3D printable pixel grid STL. No base plate, just 1mm walls around each active pixel.
Images are processed locally in your browser.
For real printing, 4-8 colors are recommended. Increase this if you want more detail.
Balanced color reduction, recommended.
Merges close colors to reduce gradients and similar shades. Higher values create fewer, more printable colors.
Adds empty space around the subject for a more centered and finished layout.
Controls the fit between blocks and the grid. Larger values make blocks looser, smaller values make them tighter.
Recommended: 0.4mm. If blocks are too tight, increase to 0.5-0.6mm. If they are too loose, decrease to 0.2-0.3mm.
Similar colors are merged to reduce extra groups caused by shadows, gradients, and highlights. For real-world making, 4-8 colors are recommended.
Bed fit
The usable area may be smaller because of slicer limits, nozzle mode, purge/wipe towers, or protected zones. Always check the final layout in your slicer.
The project ZIP includes the printable STL grid, OBJ + MTL color preview, separated color block OBJ + MTL, PNG preview, CSV color list, and README.
The color preview OBJ shows the assembled result. The separated color blocks OBJ places blocks by color group for easier printing or preparation.
