6 × 3 = 18. A hexagonal prism has 18 edges. Image caption, The vertices of a prism are at each end of the 3D shape. The number of vertices is twice the number of vertices of an end face.

look carefully at the shape of each face and the number of faces to work out which 3D shape it is. Look at the base to work out the answer. A) square pyramid. B) hexagonal pyramid. C ...

That’s exactly what [Gabe] has accomplished; he’s developed a script that takes open 3d meshes and converts them to a hexagonal pattern that, when 3D-printed on a stretched fabric, lets them ...

[David] intended to 3D print a spectrogram of a gravity wave ... He started by creating a spiral model in Fusion 360, with a hexagonal cross-section and slowly tapering off to a point.
