Design Modifications

Design Changes

Background is thinner, has a lip to rest on inside the main body of the yo-yo.

Koi now have two simplified connectors each for interfacing with the background.

New Critical Dimensions

We simulated the injection molding process for our yo-yo parts in AutoDesk MoldFlow. We found that shrinkage was around 1%, allowing us to more precisely predict our critical dimensions in preparation for actually manufacturing our parts.
