WHO WE DESIGNED FOR
Students
Mothers
Visiting Families
STEP 1
3D Modeling
Mechanical engineers 3D scan real macaron and convert into .3dm file
Model yoyo components in Solidworks:
Macaron split into shell halves
Axle
Axle caps
Ball bearing
STEP 2
Fabrication
3D resin print macaron shell halves
Hot glue on sprue for resin pouring later
Create molds out of 3D printed shells with Smooth-On Mold Star
Mix pigment with Smooth-On Smooth-Cast resin
Pour resin in molds
Vacuum seal resin in mold to prevent bubbles
Allow resin to cure for 24 hours
Remove cured resin from mold
Saw off sprue
Drill central hole for component assembly
Sand and polish for smooth finish
Assemble components with resin shells
Attach yoyo string to central axle

STEP 3
Custom Packaging
Outline dieline in Rhino3D + Illustrator
Lasercut cardboard
Fold into box and hotglue
Spraypaint interiors
Wrap in sticker wrap
Hot glue plastic window for product reveal window
Attach fabric pull tab for opening
We sold out at the market.
After the event, many buyers shared clips of them using the yoyos with friends.
Despite the various challenges the team faced, the project was a success!
1
Tactile
An experience that recalled hands-on childhood play in a time dominated by digital media
2
Small
Small enough to prototype and mass produce within a couple weeks
3
Marketable
Could sell well at the market and resonate with Gen Z consumer tastes
4
Challenge
Technical challenge for the mechanical engineers on the team


PROBLEM STATEMENT
How might we redesign a nostalgic toy for a new generation?
STICKER CUSTOMIZATION
With every purchase, Glossier gifts complementary stickers for consumers to playfully customize their products.
PACKAGING AS PRODUCT
Liquid Death uses rebellious beer-style packaging to transform water into a product with a personality. The brand is the packaging.
COLLECTIBILITY
Pop Mart's Labubu series drives repeat purchases by offering different colors each season to encourage collecting.
VIBRANT COLORWAYS
Starfaces's bold-colored, star-shaped acne patches turn everyday skincare into a form of self-expression.
