The Story I designed this because I lost the original handle for my precision screwdriver set but still had all the bits. Instead of buying a whole new kit, I printed this robust, magnetic handle.
Features
Standard Fit: Compatible with standard 4mm hex precision bits (common in electronics repair kits).
Magnetic Hold: Designed to accept a 4mm diameter magnet at the bottom of the socket. This ensures the bit snaps in satisfyingly and doesn't fall out while you are working.
High Strength: Printed with thick walls to withstand the torque needed for small screws without cracking.
Hardware Required
1x 4mm Diameter Magnet: (Round). Drop a small amount of superglue into the hole before inserting the magnet to keep it permanently fixed at the bottom.
Precision Bits: Any standard 4mm hex bit.
Print Settings
I printed this with high-detail settings to ensure the bit socket is tight and accurate.
Layer Height: 0.12 mm (Recommended for a smooth surface and accurate internal tolerances).
Infill: 25%
Infill Pattern: Honeycomb (Provides excellent internal structure for torque resistance).
Wall/Perimeter Count: 4 walls (Essential! This prevents the handle from twisting or cracking when you apply force).
Supports: No supports required if printed vertically (standing on the flat handle base).
