Color Mixing Octopus

Octopuses are a good subject for this: curved surfaces, overlapping tentacles, and a few clearly separated regions. That lets you see how cyan, magenta, yellow, black, and white blend on both flat-ish areas and surfaces that catch light from different angles.This is meant as a test/display model, not a toy with moving parts. Print it as one piece or split the body and tentacles if you want to assign different mix ratios to different regions.What it is good for

• Checking how well your translucent CMYKW set actually mixes

• Comparing layer-interleaved mixing vs painted/solid regions

• Seeing how layer height changes the blend

• A small, photogenic print for showing off a new filament set

Suggested print settings These are starting points — adjust to your printer and filament.

• Layer height: 0.08–0.12 mm for smoother optical blending. 0.16–0.20 mm works, but the mix looks more striped up close.

• Nozzle: 0.4 mm is fine

• Walls: 2–3

• Infill: 10–15% is enough

• Supports: only if your orientation needs them. Standing on the mantle with tentacles reaching down usually needs some; laying it on a flattened underside can reduce them.

• Brim: useful if the contact patch is small

• Print speed: slower outer walls help the surface look cleaner on translucent filament

Filament Designed around a translucent CMYKW set:

• C — translucent cyan

• M — translucent magenta

• Y — translucent yellow

• K — black (or translucent grey if that is what you have)

• W — white

Opaque primaries will not mix as cleanly. The effect depends on light passing through thin layers.If you are using ColorMix / Full Spectrum / similar layer-interleave workflows, keep the printable ratios simple: 1:1, 3:1, 1:3, and 1:1:1. Those read more evenly than long repeating block. How I used it Use this section to describe your actual setup. Example:I assigned different mix recipes to the mantle, head, and tentacles so I could compare several blends on one print. Printed at 0.12 mm layer height with [your slicer] on [your printer].Files List what you actually uploaded. Example:

• octopus.stl — single-body version

• octopus.3mf — pre-painted / multi-material version with color regions

• optional split parts if you included them
