This swatch is intended to show the gradient steps for a 0.2 mm layer height when using manual color changes with translucent materials, as well as the interactions between the different filament colors and other slicing settings, such as infill density.

I recommend downloading blending_swatch.3mf instead of blending_swatch.stl, and keeping the layer height set at 0.2 mm.

The filaments used in both swatches in the cover photo for this model are Prusament's PLA “Opal Green” and “Vanilla White” color variants.

-- units are in cm local layer_height = .02 local steps = 8 local depth = layer_height * steps local extent = 1 model = nil for i = 1, steps, 1 do local step = box(extent, extent, depth + (i - 1) * layer_height) :align(-1, -1, -1) if not model then model = step else model = model :move_x(extent - layer_height) :union(step) end end model = model:align(-1, -1, -1)
