Design for free. Build for real. Every invention starts as an idea — here's how we help you turn it into something you can hold in your hands.
Whether you want to explore ideas for free, get a real kit shipped, sell your inventions, or build DIY — we've got you covered.
From AI design to a real, engineered kit at your door — in five straightforward steps.
Use the free Design Studio to describe your idea. The AI creates a complete kit with parts, hardware, and instructions.
Happy with your design? Submit it for a $100 build kit. A real engineer reviews every detail for buildability.
Our engineers validate dimensions, tolerances, hardware specs, and assembly sequence. If something won’t work, they redesign it.
Approved designs go to production — birchwood laser cutting, PLA 3D printing, and hardware sorting. Every piece labeled and organized.
Everything arrives in one box, ready to build. Open it up, follow the instructions, and watch your invention come to life.
No risk: if we can't engineer a working kit, you don't pay.
Designed a kit that other kids would love? Turn it into a product. Our Inventor Program takes your engineered kit and lists it on the InventShack marketplace.
Create your kit in the Design Studio and submit for engineering.
Our team finalizes the design for mass production and creates professional listings.
Your kit gets listed on InventShack. We handle manufacturing, shipping, and support.
Receive a commission on every kit sold. Build your inventor portfolio and reputation.
Already have a 3D printer or laser cutter at home? We sell just the parts you can't easily make yourself.
Precision-cut birchwood panels, ready to assemble. The parts that are hard to make at home with the same quality.
Pre-sorted bags of screws, springs, rubber bands, and fasteners. Everything spec’d to the exact design.
Download STL files for all 3D-printed parts. Optimized for FDM printers with PLA at standard layer heights.
You’re not charged. We only charge $100 when we can deliver a working, buildable kit. If the design can’t be engineered into a functional build, you get a full explanation of what would need to change.
After submitting, engineering review takes 3–5 business days. Manufacturing and shipping add another 5–7 business days. Most kits arrive within 2 weeks of submission.
Kits can be designed for ages 5–13+. You set the age range when designing, and the AI adjusts complexity, part sizes, and safety considerations accordingly.
Yes! Through our Inventor Program, your engineered kit gets listed on the InventShack marketplace. You earn a commission on every sale — we handle all manufacturing, shipping, and customer support.
Great! Choose the DIY Maker Option. We’ll sell you just the laser-cut wood pieces and hardware packs, and provide the 3D print files so you can print the custom parts yourself.
Laser-cut parts use 3mm birchwood. 3D-printed parts use PLA (plant-based, non-toxic). Hardware includes standard stainless steel screws, springs, and rubber bands — all kid-safe.
