This is a photogrammetry 3D scan of a pair of neolithic burial chambers at the CADW Dyffryn Ardudwy site in west Wales. They are approximately 1:100 scale and both structures are provided as three separate parts so they can be printed without support material (so obviously a bit of glueing is required after printing).
