This 3D-printed small electronics screwdriver is designed for 4mm bits, featuring a modern hexagonal body and a twisty grip for comfortable handling during precision work. The tool’s snug fit ensures bits stay in place, though it may require slight adjustments for different bit sizes. Keep in mind that tolerances can vary depending on your 3D printer and filament choice, so minor adjustments might be necessary to achieve the perfect fit. The screwdriver comes in a couple of sizes to accommodate various needs in the STL files.

If this design receives good feedback, a potential future upgrade could include the ability to add a small magnet, ensuring the bits are held securely in place during use.
