Two-Color Die Puzzle, with box

This is one of the harder 9-piece puzzles you'll encounter: simply putting the pieces together to make a six-sided die. The reason it is hard is that there are bumps and cavities inside that need to line-up. but the cavities look just like the dots on the die surface. If you need some hints, there is a video of the nearly-assembled pieces spinning:

Note that the box itself is also a little puzzle. The box lid slides closed and then gravity will engage a little oval bump that will keep it from sliding open again. To open the box, simply turn the box upside down (with the 6 pattern on the bottom); the weight of the die inside will push the lid down enough to clear the bump and slide open freely. This puzzle is a pretty easy print on my Bambu with AMS. but not fast because of the filament changes and flushes. This is one of the better examples of a design where the slicer option to flush filament into infill works nicely. There are no unsupported spans, although the filament changes do offer the potential for a bit of mess.
