Students will work in three-person design companies to create, test, and refine a 3D-printed Hawaii souvenir and develop a business proposal for the Made in Hawaii Festival. They will apply engineering design, CAD fabrication, financial math, branding, and audience research while meeting size, print-time, and $1.25-per-unit cost constraints. The project centers on the question, “How can we design a Hawaii souvenir that stays under budget, fits the printer limits, and still attracts buyers at the Made in Hawaii Festival?” Teams will present their prototype, pricing, profit margin, break-even analysis, and marketing strategy in a two-minute trade-show pitch.

Students will apply the engineering design process to create, test, and revise a culturally relevant Hawaii souvenir in Tinkercad. They will use dimensions, mass, print time, and unit rates to meet a 3-by-3-inch footprint, 10-minute print limit, and COGS below $1.25. Students will calculate gross profit, profit margin, and break-even sales volume to justify a $6–$8 retail price. Teams will develop buyer-focused branding and packaging, then use a physical prototype and business proposal to explain how their product stays under budget, meets printer limits, and attracts Made in Hawaii Festival buyers.

Teams will create two labeled souvenir concept sketches and a criteria matrix comparing buyer appeal, cost, size, and print time. They will produce a Tinkercad model, exported .STL file, and tested 3D-printed prototype of a keychain, bag tag, or desk sign that stays under $1.25, within a 3-by-3-inch footprint, and under 10 minutes of print time. Each team will also create branded packaging and a business proposal with a buyer persona, $6–$8 retail price, COGS breakdown, gross profit, profit margin, and break-even sales volume. The final products will be presented together in a festival-style booth through a two-minute investor pitch and peer-reviewed gallery walk.

Stage a mini Made in Hawaii Festival with sample souvenirs, price tags, and buyer persona cards; students use mock budgets to select one product and explain what attracted them. In teams of three, students rotate through hands-on stations to measure sample products, examine 3D-printed features, estimate material and machine costs, and identify designs that fit a 3-by-3-inch footprint and 10-minute print limit. Reveal the challenge—“How can we design a Hawaii souvenir that stays under budget, fits the printer limits, and still attracts buyers at the Made in Hawaii Festival?”—then have teams record initial design ideas and questions. Close with a quick share-out connecting buyer appeal to the $1.25 production budget and $6–$8 retail range.

Host a classroom Made in Hawaii Trade Show where each team displays its 3D-printed souvenir, packaging card, and business proposal at a branded booth. Teams deliver a two-minute pitch explaining how their product attracts a target buyer while staying under the $1.25 unit budget, 3-by-3-inch footprint, and 10-minute print limit. Families, school staff, local makers, or business partners circulate as festival buyers, ask financial and design questions, and use feedback cards to evaluate product appeal, branding, math accuracy, and feasibility. Conclude with audience-choice recognitions such as Best Buyer Appeal, Strongest Business Plan, and Most Resource-Efficient Design.
