Unearthing New Frontiers: Alternative Builds for LEGO Set 31115-1 “Space Mining Mech”

From the moment any LEGO Creator 3-in-1 set lands on your desk, a universe of creative possibilities unfurls. With the 31115-1 Space Mining Mech, the core model’s chunky treads, articulated arms, and futuristic cockpit whisper of untold adventures on distant asteroids. Yet, as with every Creator bundle, the real magic lies not only in the official build but also in the ingenious alternate designs dreamed up by the community. Each of these MOCs—or My Own Creations—takes the same pack of pieces and reimagines them into machines that range from graceful starfighters to massive submarines, from insectoid walkers to chibi-style power suits.

Imagine piloting an AT-ST-style walker across a barren moonscape, its binocular eyes trained on an alien crystal vein. Picture a sleek X-Wing Starfighter, repurposing mining drills into wing-mounted lasers so you can dogfight smugglers at lightspeed. Envision a deep-sea submarine, its hull pressurized by the very same parts meant to carve through rock, now protecting you against crushing oceanic depths. Each design speaks to a different facet of exploration—surface, atmosphere, and deep ocean—reminding us that no frontier is too distant for our brick-built dreams.

As you scroll through the examples below, ask yourself: what stories can you tell with these alternate builds? Where do they take you? Whether you’re drawn to towering mechs or miniature chibi suits, these community creations will spark fresh ideas for your own LEGO expeditions. Ready your toolkit—and let’s dive into the twenty most imaginative transformations of the humble Space Mining Mech.
