🔧Compact rotating-base screwdriver for 4 mm bits. Print-in-place design, strong, fast, and ready for daily use. 🛠️

Printing Instructions

• Print in PLA or PETG at 0.2 mm layer height, 3 perimeters, and 15 % triangle infill.
• Arachne wall generator works best
• No supports required — just add a small brim if your bed adhesion is weak.
• After printing, twist the base gently to free its rotation.
• Bits press-fit firmly, but a small drop of super glue can be used for permanent fixation if needed.

Optional: perform a mid-print color change (8,80mm) to differentiate the handle base.

Description

The Precision Screwdriver for 4 mm Bits is a compact, ergonomic tool designed for makers who use the same precision bits repeatedly and want them always at hand.

Its rotating base mimics professional precision screwdrivers, giving smooth control while tightening or loosening small screws. 

The press-fit shaft holds any standard 4 mm bit securely without needing magnets or metal parts.

This print-in-place design is quick to print, requires no supports, and produces a durable, comfortable grip ideal for electronics, RC repairs, and small assemblies. The handle shape provides natural finger alignment and improved torque.

By printing multiple handles in different colors, you can instantly identify your favorite bits — Phillips, Torx, flat, or hex — at a glance. A simple idea that streamlines your workspace.

Functional, fast, and satisfying to print, this design blends precision engineering and maker practicality, turning a daily tool into a customizable print you’ll actually use.
