Mini 4mm Bit Holder with Magnetic Lock – Ultra-Compact & Easy Print

This is a compact and ergonomic handle designed to hold a 4mm screwdriver bit. The handle features a hexagonal shape for a comfortable grip and includes an internal slot to insert a small cylindrical magnet (5 mm diameter x 3 mm height) to secure the bit in place and prevent it from slipping out during use.

Features:

• Fits standard 4mm bits.
• Internal slot for a 5x3 mm cylindrical magnet.
• Compact, minimal design ideal for tight spaces or carrying in a tool pouch.
• Ergonomic shape for a better grip.

Printing Instructions:

• Orientation: Print standing on one of the flat ends for maximum strength.
• Layer Height: 0.2 mm (or finer).
• Infill: 20% (increase if extra strength is needed).
• Supports: Not required.
• Material: PLA, PETG, or ABS.
• Adhesion: Use a brim to improve bed adhesion.
• Pause: Insert a print pause (M601) at the correct layer to place the magnet during the print. Resume printing after the magnet is inserted and properly positioned.

Assembly:

1. Start the print and insert the 5x3 mm magnet when prompted by the pause (M601).
2. Resume the print to encapsulate the magnet inside the handle.
3. Once the print is finished, push your bit through the handle. The magnet will hold it securely.
4. Ready to use!
