Himitsu Bako 5 | 214 Step Japanese Puzzlebox

Himitsu Bako 5 — Breaking 200!

In the quiet discipline of the workshop, a true puzzle is not hurried—it is earned.

Himitsu Bako 5 is the next chapter from 2222pzzls, created for those who believed the journey would end at 90 steps. Though remarkably compact—comparable in size to the SE series—it conceals an astonishing 214 deliberate movements before it reveals its heart.

Crafted in the spirit of the traditional Japanese Himitsu Bako, this is not merely a puzzle where the outside panels come apart when you open it, but a true secret box. Beneath its disciplined exterior lies a generous inner compartment, designed to safeguard your most precious valuables—kept secure until the final movement is mastered.

Each surface is adorned with an intricate kumiko-inspired pattern, transforming even a single-color finish into an artwork of quiet refinement. Slide hidden switches. Shift panels with mindful precision. Open the lid step by step, as patience becomes your greatest tool.

Only steady hands and a tranquil mind will reach the treasure within.
 

Will you endure the full path of 214 steps like a true master?

Attention:
This model contains moving parts and relies on tight tolerances. It is strongly recommended to print using a relatively new or well-maintained nozzle. Worn or heavily used nozzles may result in inaccurate prints, which can cause parts to fuse together or fail to meet the required tolerances. This may prevent components from moving correctly or cause them to become stuck. BambuLab Filiament is HIGHLY RECOMMENDED! Other brands like Elegoo, have proven to give terrible results in tolerances.
