Eclipse Lamp TPU cement mold

This is a file to print a TPU mold to create an Eclipse lamp with non shrinking cement. 

The sphere is in two parts and the arc is in 3 parts. I taped them together with painters tape tightly and then applied a silicone spray lubricant to allow the moulds to release from the cement. Petroleum Jelly would also work.

Eclipse is a 3D-printed sculptural light that blends brutalist form with celestial elegance. Designed around a minimal arch and centered orb, the lamp evokes the quiet drama of an eclipse—its integrated LED ring casting a soft, radiant glow that frames the matte-textured sphere. The LED strip used is this one, embedded into the arch and diffused through a 3D-printed translucent PETG channel for a smooth, even light. Entirely 3D printed aside from the LED, Eclipse celebrates precision, material honesty, and a modular spirit. Whether placed on a desk, shelf, or bedside table, it functions as both ambient lighting and a contemplative design object—ideal for makers, designers, and lovers of functional art.
