Three-colour Penrose P2 tiles
Roger Penrose's Kite and dart tiling, aka P2. The default tile side of 15 mm is a bit small, so you might want to make it larger.
The outside angles are very slightly rounded to make them easier to print. You can turn this off in the OpenSCAD code if you want.
The penrose_p2-draw.svg file is for you to make your own manual tilings in Inkscape.
