Hourglass Sand-Timer Form

A smooth, 3D-printable hourglass form — two rounded bulbs meeting at a pinched waist, the shape that has meant 'time' for centuries. Simple, symmetrical and instantly recognisable, it makes a calm little sculptural object with no fuss. Because of the narrow waist it prints most cleanly split into top and bottom halves and joined, or upright with light supports through the neck; a smooth layer height keeps the curves clean. Stand it on a desk, a shelf, or a windowsill as a minimalist ornament, a paperweight, or a quiet nod to making time count. A classic form, pared back to its essentials.
