Two styles of road cones, one normal and one tall. The taller cones are similar to the ones often seen in Britain for road works, while the normal sized cone is similar to those you see for cornering off utility work or restricted parking.
The cones feature a rounded beveled base (as pictured). The cones can be printed in orange PLA or you can try reflective PLA for some extra effects. The 3D view (black) incorrectly shows a square (not rounded) base due to a limitation in Blender related to beveling and glTF exporting. The cones will print as shown in the image (blue).
