Ultimate Modular Tool Handle

Ultimate Modular Tool Handle (Screwdriver & Jig Saw)

 Transform your 3D printer into a functional tool factory with this fully 3D-printable, highly versatile modular handle!

Designed with both ergonomics and engineering in mind, this tool handle features a robust collet mechanism that allows you to seamlessly switch between standard 1/4" hex screwdriver bits and standard jig saw blades. Whether you need a stubby screwdriver for tight spaces or a compact hand saw for quick cuts, this tool has you covered.

 🌟 Key Features:

• Dual-Purpose Collet System: Comes with interchangeable collets specifically designed to tightly grip either hex bits or jig saw blades. The threaded collar ensures a secure, wobble-free lock.

• Hidden Storage Compartment: The hollow handle design features a sleek screw cap at the base, providing a convenient internal storage space for your spare bits. Never lose a bit again!

• Ergonomic Grip: The contoured handle features strategic grooves for maximum torque when driving screws and a comfortable, slip-resistant grip when sawing.

• No Extra Hardware Required: 100% 3D printed parts. No metal screws, nuts, or glue needed for assembly.

🖨 Printing Recommendations:

To ensure the tool is strong enough for real-world use, please follow these print settings:

• Material: PETG is highly recommended. It provides the necessary layer adhesion, impact resistance, and slight flexibility needed for the collet jaws and threaded parts to function perfectly without snapping.

• Infill: Honeycomb pattern is highly recommended for optimal strength-to-weight ratio and structural integrity during twisting motions.

• Infill Density: 15-20% (depending on how heavy-duty you want it to be).

• Wall/Perimeter count: Minimum of 2-3 walls to reinforce the threaded sections and the collets.

• Supports: Designed to be printed completely support-free!

📁 Included Files:

Alongside the individual STL files, ready-to-print profiles (3MF) are included to save you time and ensure the best tolerances right off the build plate.

 Happy printing and making! If you make one, please share your makes and let me know what color combinations you chose!
