As I was browsing the internet looking for some things to make with my laser I saw some shelves like this but larger. Got me to thinking about making a scaled downed version with the laser. I am limited to 12" on my machine, but a bigger laser can make them longer and taller and thicker. Very customizable Highly configurable Stackable Sides can be placed in unlimited position on each to make them all look a little different. Use different acrylic colors. There is no front, no back. No top, no bottom. No left, no right. The only limitations are one's creativity and imagination.
