This is a traditional japanese puzzle box / secret box based on the instructions I found on

Originally meant to be wood, a 3D print fits perfectly. I have contacted the author and have his approval to create the 3D models and post them here on Thingiverse.
I added the ornaments for every sides.
The dimensions proposed here are 96mmx96mm leaving you with a center space, for your treasure, of 40x32mm and 64mm height.
The default proposed files are at exact dimensions, because the ancient Japanese puzzle boxes were a very precise hand work. You will need some filling and sanding to fit all the pieces correctly together. The aim is that nothing moves by itself, that the user needs a slight force to push the sides.
As I don't know how exact your printer is and how motivated you are, I also included a zip containing fitted parts. They have 0.2mm less on every sides that should glide, thus requiring less fitting after printing. Only the bottom and top parts are fitted, the side parts are the same!
Each version comes with every parts doubled, one having the carvings for the ornaments and the other without
For opening and closing instructions, you can either check my video or the pdf document
I do hope you enjoy this box and my work
Stay tuned, as I'm actually designing the next one, the Chines Dragon box
