**Modular Tool Holder System for Prusa Core One/+**
The main focus of this system is flexibility. You can build the tool holder exactly to your needs, rearrange it at any time, and expand it as your tool collection grows — all while keeping a clean, stable setup directly on your 3D printer.

Base modules can be connected side-to-side, allowing the tool holder to be expanded horizontally to any width. Onto each base module, you can attach a variety of tool holders designed for different tools, such as pliers, Torx drivers, screwdrivers, brass brushes, wrenches, sockets, and more. Some holders are universal, making them suitable for multiple tools or general-purpose storage.
