| Materials | Laser-cut wood, 3D-printed PLA, real hardware | Cardboard, foam, stickers |
| Mechanisms | Gears, springs, axles — things that move | Static or simple |
| Age Tuning | Exact age and skill level | Broad age ranges |
| Replayability | Real builds that last | Often single-use crafts |
| Learning | Engineering principles in every build | Varies widely |
Describe anything — a marble machine, a treasure box with a lock, a wind-powered car. The AI handles the engineering.
Select the age range and difficulty. Younger kids get simpler connections and bigger pieces. Older kids get gears and complex mechanisms.
Choose between laser-cut birchwood, 3D-printed PLA, or a mix. Parts can range from pocket-sized to desktop builds.
Not quite right? Tell the AI to change colors, add features, simplify a mechanism, or swap parts. Unlimited revisions.
Every InventShack kit uses real engineering materials — not cardboard and tape. Precision laser-cut birchwood panels, custom 3D-printed PLA brackets and gears, and real hardware like stainless steel screws, springs, and rubber bands.
The result is a build that feels substantial, works mechanically, and lasts. Kids learn what real materials can do — the strength of wood, the flexibility of PLA, the tension of a spring — through hands-on experience.
A custom building kit makes an unforgettable gift. Instead of a generic toy, give a child a kit designed specifically around their passion — whether that's dinosaurs, space, vehicles, or contraptions that launch things across the room.
A one-of-a-kind invention kit designed around their favorite thing.
A hands-on project they'll actually build, not just unwrap and forget.
Spark curiosity in engineering, design, and problem-solving.
