Introduction

Welcome to the ToolheadBuilder catalog — a curated, community‑driven index of modern 3D‑printing components. This page brings together information from several independent GitHub repositories, each dedicated to documenting a specific part of the motion system: extruders, toolheads, and hotends. While each repo stands on its own, this site unifies them into a single, searchable reference for anyone exploring the rapidly evolving ecosystem of open‑source printer hardware.

From here, go pick out your toolhead. This will drive what extruders and hotends it natively supports. From there, take a look at all your extruder and hotend options to see what fits your build best.

Each page serves as a catalog of community projects to make them easier to browse through. Together, these repos form a modular compatibility map: choose an extruder, pair it with a toolhead, match it to a hotend, and you have a complete, buildable extrusion system.
