this is a cube in a cube in a cube. On a small scale it prints well without supports but they will be needed if you make the cube bigger. Infill can be as low as 5% and you should just experiment with it I guess. There will be other things in the strange collection soon enough. Also if for some inexplicable reason the print just stops on you (it happens) it does not matter much because it will just seem like the cube is just melted into the surface you are displaying it on. it happened to me while i was trying to waste the filament tat was still in the printer and things went well.

it makes me feel powerful while holding it

the blend file is in the downloads if u want to do something with it
