The Enchanting Lock-Nessie Our 3D printed Lock Nessy is now available. The legend of the Loch Ness Monster, often nicknamed Nessie, has roots in a 6th-century account of a creature encountered near Loch Ness by Saint Columba, an Irish monk. Modern sightings and interest began in the 1930s, fuelled by reports and a photograph that, while initially considered evidence, was later revealed as a hoax. Despite numerous investigations and sightings, the existence of the Loch Ness Monster remains unproven, until now.
