First, I needed a way to hang the trellis for my peas and green beans. There was already a cable stretched over the top of this long bed, so I just needed a way to attach the netting to the cable. Rather than tie the netting to the cable with twine or wire, I wanted a solution that would lower the net a bit so it would be easier to secure at the bottom. To do this, I designed a small hook several inches long that could be printed quickly several at a time. Here is the finished garden trellis netting hook on Thingiverse. Undoubtedly it has other applications as well, especially since the openSCAD file is parametric and can easily be tuned to different dimensions.
I use a hybrid system to lay out my garden, a combination of square foot gardening and hexagonal plant spacing. Hexagonal spacing provides an aesthetic sense or order in the garden, but it also has many benefits to the plants. When planted in a tight hexagonal pattern, the leaves of plants will shade the soil, which keeps the soil cooler and slows evaporation. The denser spacing also helps control weeds because the established garden plants will work to crowd weeds out and keep them from coming in. Lastly, tighter spacing means you can get more produce per square foot from your garden (you may get less per plant, but with more plants you get more per square foot). For more information about hexagonal spacing, as well as a holistic approach to organic gardening, see How to Grow More Vegetables by John Jeavons. You can also see this reference on the spacing method as it applies to companion planting.
This kind of spacing isn’t too hard to do by hand, but is much faster and easier with a tool to help. This seed spacer was designed to place holes at fixed distances which you can then put the seeds in. Just press the spacer into the soil to make three holes, then lift, rotate, and position the spacer with two of the prongs in two of the previously made holes; repeat….
