Anyone know how to make this type of stone storage?

Hi, happy New Year!

Was wondering if anyone knows how to make one of these: https://ebay.us/cMvUFg
Wood is fine too; I don’t have the skills so am willing to buy.

Thank you,

He most likely uses a 3d printer. I would say if you like it buy it. If you don’t have tools or materials you would probably spend more money for your materials and then you still need to fabricate it. Just buy it
