Re: PSFK | A Wearable Planter

Now you can get fresh oxygen under your nose all the time! Well, at least the times when wearing this necklace. Now, this would be a cool thing to 3D Print, yeah? Customize your own Planter Necklace. How about your own Planter Belt Charm? 

There may be a few iterations in the design so you don’t get dirt specks all over your shirt, but still.. novel idea!
