I need up to fifteen original DIY cardboard kits that 4- to 7-year-olds can pop out, fold and proudly display. Think bright, cartoonish animals, cheerful cars and playful landscape elements—each kit should feel like a little world that snaps together in minutes without adult frustration. Here is what will make this project a success for me: • A fully resolved 3-D form for every character or scene, planned specifically for E-flute or comparable board. • Production-ready vector files (AI, PDF, SVG) that include die-cut lines, fold scores, glue tabs, bleed and safety margins. • Clear, kid-level assembly logic illustrated right on the sheet or in a one-page guide. • Precise dimensions so the manufacturer can run plates without a second round of pre-press questions. The structures must be sturdy enough for small hands yet simple enough to finish in under 15 minutes; no extra tools beyond school scissors and stick glue. If you already prototype in Pepakura, Blender, Illustrator, or similar, let me know—whatever pipeline you prefer is fine as long as the final art is clean, layered vectors. I will review the first kit as a proof of concept before green-lighting the remaining designs, so please factor that micro-iteration into your timeline. Looking forward to seeing how you transform flat sheets into charming, stand-up adventures.
