What You'll Need
- You will need brikit.app - kid-friendly interface, creative model suggestions, and printable instructions. Which parents would not love getting kids building again without buying more!
- Smartphone + Lego stash
What Might Be Challenging:
- Brikit requires a clear photo of Lego pieces — too many scattered bricks = poor recognition
- Some stores won’t take DIY set, and you need to be ready to use Facebook marketplace
- Presentation matters! Perfect timing to give kids guidance on value based pricing
- Kids may need guidance on value-based pricing and negotiation
- No-App Alternative - "Use Lego's free Digital Designer → Parent warning: 'Takes 3x longer without AI scanning!'"
Dive In
Step 1: Sort Your Lego Pile
Group by color or size if possible. This helps Brikit generate better results.
Step 2: Open Brikit.app and Snap a Photo
Take a clear photo (on a flat surface) of your bricks.
Step 3: Generate Rebuild Ideas
Brikit will suggest 1–3 models your bricks can become — from animals to cars to fantasy mini builds!
Step 4: Choose One (or All!) and Build
Use the on-screen instructions, or print them if you want a physical guide.
Step 5: Print and Package Your Model
Print out the build instructions and a photo of your final creation. Place everything — including the Lego build — into a small box or bag.
Pro tip: Include two sets of instructions so the buyer can rebuild it or gift one to a friend — that’s bonus value!
Step 6: Find a Store or Marketplace
Check with local toy resale shops or consignment stores — many welcome DIY Lego kits if they’re well-packaged and complete.If not, try online platforms like eBay, Facebook Marketplace, or even your local kidpreneur market.
Step 7 (Optional): Negotiate the Price
Have your child practice their pitch:
- “This kit includes a dragon you can build with 24 bricks!”
- Offer a discount if they buy more than one.
Step 8 (Optional): Create a Mini Catalog
Print or draw 2–3 rebuild ideas and offer them as a bundle set!
What else you can do with it
