🪛 Mini Screwdriver with Bit Storage – 3D Print

This model is a compact mini screwdriver designed for precision tasks such as 3D printer maintenance, small repairs, or everyday desk use.

The handle also works as a bit storage compartment. The bits are stored in a screw-on cap, which prevents them from falling out and keeps the most commonly used bits always within reach.

Both the screwdriver and the storage cap feature embedded magnets, which:

• securely hold the working bit in place,
• keep the stored bits from moving,
• allow for quick and easy bit changes.

The ergonomic, textured handle provides a comfortable and secure grip, despite the compact size of the tool.

✨ Features

• built-in bit storage inside the handle
• screw-on storage cap
• magnet slots for secure bit retention
• compact size – perfect for desk or tool bag
• ergonomic, anti-slip grip

🖨️ 3D Printing

The model requires magnets: D20×3 mm Round Magnet and D12×3 mm Round Magnet from Maker's Supply

The magnets are embedded inside the model during printing. In the provided 3MF file, the correct layer pauses are already set at the appropriate moments for inserting the magnets. The magnet pockets are designed as a tight press fit, so the magnets will not fall out or move during printing.

The handle must be printed with supports, set to build plate only. Without this setting, supports will be generated inside the magnet pocket, making it impossible to insert the magnet.
The pause for inserting the D12×3 mm magnet occurs at the beginning of layer 256 when using a 0.2 mm layer height.

For the cap with bit storage, supports are not required, but they improve thread quality. If you enable supports, also set them to build plate only to prevent supports from being printed inside the magnet pocket.
The pause for inserting the D20×3 mm magnet occurs at the beginning of layer 48, with a 0.2 mm layer height.

Have fun printing, and I hope my design proves useful in your everyday life! 😊
