31378-1 Creator 2026 278 parts 8.8% catalog rarity Intermediate

The LEGO Creator 3-in-1 Space Exploration Telescope (31378-1) provides adaptable exploration with its 278 pieces. Construct a telescope on a tripod, featuring a solar system model with the sun and seven spinning planets. An integrated light brick projects images from three interchangeable lenses—depicting a planet, a star, or the Moon—onto any surface. The set rebuilds into a microscope, using its light brick to illuminate observed details. Alternatively, assemble a UFO model with antennae and flip-out legs for display, which beams light from underneath. This Creator set encourages scientific and cosmic exploration through its distinct models.
