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.
