Inspired by the tool holder in the newer HSW remixes; this is a fully parameterized version of the hexagonal tool holder. It depends on the HSW OpenSCAD library and the Hexagonal Grid Generator library.
This model requires the Updated OpenSCAD library for HSW attachments which you can find here: https://www.printables.com/model/542305-updated-openscad-library-for-hsw-attachments
This model requires the Hexagonal Grid Generator library which you can find here: https://www.printables.com/model/86604-hexagonal-grid-generator-in-openscad
This model requires the The Belfry OpenSCAD Library V2 which can be found here: https://github.com/revarbat/BOSL2
Typical parameters you use for your HSW components should work. I print on PLA+ but you should use whatever material your wall is made of I suspect.
