Umbrella v1.5

DesignedFeb 2016
Crease PatternYes

This is an update of my first umbrella (Umbrella v1) model. Umbrella v1 tended to spring apart when folded out of normal kami origami paper due to paper bulk in the umbrella top region and a poor locking mechanism. When I taught that first version at the 2015 OrigaMIT convention, I received more feedback that motivated me to clean up and redesign v1. For the new version, the umbrella top and handle proportions are the same, but the paper layers are distributed more evenly and the grip design is cleaner. The new version utilizes a more secure locking method to make the umbrella top curved as well.
