The model of this screwdriver, much like the previous manual drill model , was initially developed for use with a multi-filament 3D printer. Specifically, it was designed for the Geeetech Mizar M 3D printer . This printer is equipped with two print heads that are interchangeable, allowing for the printing of separate filaments to achieve various colors and blending, enabling the creation of gradient transitions.
 

However, recognizing that most printers use monofilament, I designed the model to be a solid piece, with the option to separate components for subsequent assembly using glue. For instance, the main handle can be divided in a slicer, enabling you to print the ring in a different color and then easily assemble it into a cohesive whole. Additionally, there's a model with a reinforced platform that can be detached after printing, providing a high degree of fixation, especially considering differences in printers and adhesion challenges in many cases. Thus, there are several available options, offering you a choice according to your preferences.

When I created the manual drill model , published earlier, I thought that a similar approach could be applied to design a handle for a 4mm bit screwdriver.
