ToolCore Modular Driver System

This is a fully 3D-printable modular screwdriver system designed for maximum efficiency and organization.

The model includes:

Modular bit holder cubes that can be snapped together using integrated latching connectors. Configure the layout to your workspace or toolbox.

Cartridge-style bit holders ("stems") that secure individual screwdriver bits. These holders can be quickly swapped between the driver and the base unit.

A custom driver handle featuring a snap-in locking mechanism for fast, secure engagement of bit holders.

A release button on the screwdriver handle allows one-handed switching of bits – simply eject the current bit holder and insert it into any open slot in the cube base.

Designed for rapid workflow: pick a new bit by docking the handle onto the desired stem. No need to touch the bit itself.

Includes label plates for common bit types:

H2, H3, H4, T10, T15, T20, SL4, SL5, SL6, PH1, PH2, PH3, PZ1, PZ2, PZ3

Need a custom bit name or unique label for your setup? The author offers the option to generate custom bit tag plates upon request. Personalize your system for your exact workflow.

This design is ideal for makers, technicians, or anyone who wants a compact, modular, and highly usable way to store and swap screwdriver bits. The aesthetic is clean and color-customizable for easy visual sorting. Whether you're printing it for personal use or as a gift for a fellow maker, the ToolCore Modular Driver System is a functional and stylish upgrade to any toolbench.

Also included are 5 interchangeable bit holders with slightly different inner diameters, allowing you to test and choose which fit works best with your bits. This ensures optimal grip and retention no matter what brand or batch of bits you use.
