Puzzle Cube with Box

This is a 6-piece 3x3 puzzle cube I made for my kids, with a nice box and logo on the lid for multicolor printers. There's also a file for a lid without logo for single color printers. Dimensions of the cube are 6x6x6cm.

Some adults struggled to solve it but the kids figured it out after some minutes. I won't post the solution therefore unless someone absolutely cannot solve it.

Print Instructions
----------------------
- Print all 6 Pieces.stl - arrange them without overhangs as shown in the Slic3r screenshot
- Print the Box.stl
- For Multicolor print Lid_with_LOGO.stl and LOGO.stl with different colors at once
- For Singlecolor print Lid_SINGLE.stl

*Note: print the pieces with "Seam position random" to have the pieces fit together evenly. For the Box and Lid use "rear" or "aligned" unless you plan to fine-grind it.*
