A small planter that fits a 3" nursery pot (76mm inner diameter) with a spiky geometric pattern on the outside
 

This isn't a very original design, but I created it to learn how to better use the CAD program I'm using. It turned out really well, so I printed it! But I used some Turbo PLA with a high layer height. I think it gave it a cool effect, but I had originally planned to print it in a marble PLA with more detail.
