"Tool Hanger" was made with Tinkercad. Edit it online https://www.tinkercad.com/things/fB9n7P9KAa3
No need for screws or any mounting stuff. Just slides right onto either side of the Robo 3D R1. This tool holder is obviously for MY tools, feel free to edit it for your tools. Takes about 22 hours to print.
