3D printing settings Want the multiple color look from the photos? You can easily achieve this by: – painting or spraying the raised details with acrylic paint, or – using the paint tool in your slicer (Bambu Studio, PrusaSlicer, Cura, etc.), or – printing with multi-color / filament swaps. The details are slightly raised on purpose, so coloring them is quick and easy.

This is a single-color STL file. Multi-color printing requires manual painting in your slicer.
