Aquarium - Root Tab Placement Tool

thingiverse

This tool makes placing root tabs simple and disrupts the substrate as little as possible. The design features a threaded and removable tip that lets you use the device for various sizes of root tabs at minimal cost. The included tip fits snugly on "00" sized gel caps, which are the most commonly used size. I created and tested this tool specifically with Thrive Caps in mind; other brands should also work, but I haven't personally tried any.
