The empty cube, household decoration

Hi guys! The intresting cube that you saw a while ago was simply a prototype of my new project, the empty cube! I recomend printing it with PLA Metal, and please give me some feedback so I can make this model a good household decoration! I reccomend printing with Pla Metal, Galaxy, Marble, Silk, Sparkle, Wood, Glow in the dark if you want a short time night lamp, and mabye PETG translucent. Thank you!
