Each color prints as a separate flat piece on the same layer
Detail is how sharp the print is — more pixels means finer detail, like DPI on a photo. It does not set the physical size (you'll set that under Export as Print size). 500px is a good default; use 800–1000px for fine detail, or lower for a quick test.
For transparent PNGs, the alpha channel is used automatically — no tolerance needed. For solid backgrounds, flood-fills from all 4 corners. Raise tolerance if fringe remains around edges.
For enclosed gaps the outer Background Removal can't reach. Turn on the cut tool, then click a gap on the Original image (top panel) to punch it through as a real hole. Click a cut again to restore it. Results show in the Color Preview.
Detects the main colors in your image using k-means clustering. Each color becomes a separate flat STL piece. Click a swatch to adjust a detected color. Uncheck a color to exclude it from export.
Add a mounting point: a hole punched through the print, or a ring loop on the edge.
Builds a solid base plate in your base color, with the image sitting flush on top as a thin skin. Each top color exports as its own STL (Load them together in your slicer and assign filament colors per object.
⚠ This is your final size — import into your slicer and print at 100%. Resizing in the slicer will change the printed size.
