The Answer.

Also, just having fun trying out a some 3D CAD and printing ideas. More versions on the way.

This one : 42 Vertex Cube

You must view the cube from a specific angle to see the 42.

Print instructions

Print in PLA using the 3mf file provided.

The best way to print the cube is "vertex down" with supports. I also used a "floating support blocker" to remove some extraneous support material from the top of the print. When printed this way no infill at all is needed.

Printing the cube on any of the flat sides without supports will NOT work (ask me how I know!).
