Ombre dyed 3D printed folding fan

So, in my ongoing experiments with 3D printing applications in our field, here's a fun new project!

I came across the freeware file for this Chinese folding fan on Thingiverse, which prints all in one--no assembly required. Cool! So i had the folks at the Makerspace here on the UNC campus 3D-print me a copy so i could test it as a fan prototype, figuring that if the file was sound and the mechanism functional, it would serve as a potential template for any number of other folding fan desig...
