I came across an intriguing video on YouTube - https://www.youtube.com/watch?v=fD-zIUYhHps - and decided to take on the challenge of deciphering its mechanics and replicating it in SolidWorks. After some perseverance, I finally cracked the code and figured out how it works. Although I haven't yet printed this design due to a pending replacement print bed delivery, I'm confident that it will be problem-free, making it safe to print once received. Building three of these units would yield a 4-inch cube, which may require scaling down for optimal printing results.
