You can build a scaffolding for your tomato plants, using this joint and sections of plastic pipe. The joint features openings at 120 degrees around the circumference, and openings at top and bottom to build towers of any height. While the joint offered here is too expensive for garden use, the stl file can be downloaded for free, and you can make as many joints as you need for your garden. If by chance you are the owner of a plastics factory, and can make these joints so they can be sold at retail for a dollar or less, please let me know.
