Customizable planter holders

**Do not use these to hang pots where they could fall on people**

I bought these quarter-sphere planter boxes without realizing how poorly designed they were for actually being hung on anything. They just have a ridge on the back, with a little notch on either end. I used OpenSCAD to make these holders fitting the notch, so that they would be kept in place sideways. Using PLA, they lasted for a full summer on a south-facing balcony, though with some distortion noticeable afterwards. Depending on your filament and printing quality, they may or may not hold up as well, so please don't use them to hang pots where they could fall on people. You might want to try [baking the prints](https://hackaday.com/2017/03/24/half-baked-idea-put-your-pla-in-the-oven/) or [other ways to strengthen them](http://www.3ders.org/articles/20141010-a-few-ways-to-strengthen-3d-printed-parts.html).
