BOXOI2-Lite: Miniature 3D Zoetrope

I published my design of a 3D zoetrope DIY kit in the instructables.com. The original intention was to make a low-in-cost, compact, easy-to-build 3D zoetrope for personal collection purposes. I then further simplify it so that it should be easy for school kids as a science project. This is the lite version of said project, where most parts can be 3D printed, and a smartphone with a strobe light app will be used in substitute for the PCBA.
