Smaller Hoffman packing puzzle

Remix for those without Fusion 360, who want a slightly smaller version.
Warning: also small fingers required :-)

You need to print the cube, the lid and 27 cuboids:
-1 x 'Cube.stl'
-1 x 'Cube lid.stl'
-27 x 'Cuboid.stl' or 3 x '9Cuboids.stl'
I printed them in 3 batches of 9 in different colors, hence the stl with 9 cuboids.
There is also a single stl file with all parts if you have a big build plate.
