OpenSCAD doesn't do textures. Neither does STL format. You could add raised text, protruding from the model. import("your_stl.stl"); translate([x,y,z]) // to move to the position where you want text rotate([x,y,z]) // to align with the face of the stl linear_extrude(height=3, convexity=6) text("your text"); Nageswara rao wrote > Hello!
