Summary

Used like staples to anchor light plants to the substrate. Designed for use on small gravel but might work for others as well. Print with 100% infill (solid) so it doesn't float, then use it to clip down plants like guppy grass or java moss until they can anchor themselves. The larger one has a wider base if needed but so far the standard one has worked fine for most plants. Added an extra wide anchor for those plants with a big root clump.
