LEGO SET 10300 - Alternate build | Back to the Future Time Machine

Immerse yourself in the world of creative reinvention as you dust off the iconic gull-wing doors of the 10300-1 Back to the Future Time Machine and reassemble its 1,053 pieces into something wholly unexpected. Picture the gleaming steel panels repurposed into the angular curves of a vintage Mustang, or the flux capacitor’s alien glow reimagined as the ominous optics of a Cybertruck. Every part in this set—right down to those tiny lever elements—holds untold potential to spark your next masterpiece.

By exploring these 17 fan-designed alternate builds, you’ll discover how designers from around the globe have taken the same parts inventory and birthed machines of war, automobile legends, and even pinball arcades. Whether you’re a seasoned AFOL looking for a fresh weekend project or a newcomer eager to learn advanced SNOT (studs-not-on-top) techniques, these MOCs invite you to stretch your imagination. The ingenuity required to transform a DeLorean—or any part of it—into something entirely new will sharpen your building skills, deepen your understanding of Technic connections, and leave you buzzing with inspiration for your own custom creations.

Below, dive into each model: click through to build instructions, admire how designers have tweaked proportions, and imagine how you might tweak them further. Ready to break the time-space continuum of LEGO design? Let’s roll back—or fast-forward—the clock on creativity.
