The Expanding Box puzzle (6 identical -easy to print- pieces)

The Expanding Box Puzzle This is my version of the **Expanding Box puzzle**, which I've adapted from this book: https://johnrausch.com/PuzzlingWorld/chap12.htm#p1. To make it more accessible, I've added some helpful tips to complete the cube, inspired by https://www.thingiverse.com/thing:3073646. This is a challenging coordinate-motion object with 6 identical pieces, and as Steward T. Coffin so aptly puts it: "*It is more of an amusement than a puzzle.*" Watch the mechanism in action here: https://youtu.be/vyYtZZor6h4. Printing this model is a breeze - no supports are needed, and even a 0.2 precision works beautifully. My version features a 40mm cube with a 0.25mm gap, but I've also included a 45mm cube for added variety. If you'd like to create your own model, I've provided a .scad file. Feel free to share your pictures and comments - I'm excited to see how you tackle this puzzle!
