Planters made with a 3d printer
3d printer technology is here to stay; with it, you can print whatever you like, and many pages provide you with the patterns of whatever shape you are looking for, from toys to missing pieces of appliances or, as in this case: planters for your succulents.
If you are fortunate enough to have a 3d printer, just search for a pattern you like and in which your plants look good. If you don’t happen to have one, you can buy them already made on eBay. You can even order more detailed designs, but that depends on you.
