I got some Easy Root Tabs from Aquarium Co-op to add to my fishtanks, and well the very first problem I had was my low success rate of using planting tweezers to bury them into the substrate. I know I can put my long gloves on and push then in by hand, but I decided to try my hand at designing a printable tool to be used with my tweezers to assist.

Behold, my root tab capsule substrate pusher thingy :) Intended to be used with a planting tweezer, one would use this to push the capsule into the substrate, shimmying the tool as it digs into the substrate. The holes are functional; they are intended to let (fine) substrate through so it would end up burying the capsule underneath.

Enjoy!
