Left-handed adaptation of the Logitech MX Master 3S mouse successfully 3D printed by a user, addressing the original design's button arrangement made for right-handed users.

In a world where technology is designed primarily for right-handed users, a creative solution has emerged for left-handed individuals seeking to use the Logitech MX Master 3S gaming mouse. An open-source 3D printing project, led by an unnamed enthusiast, has resulted in a left-handed version of the popular mouse.

The project, available for download at Printables, involves 3D-printing a left-handed version of the Logitech MX Master 3S. This modification opens up the Logitech MX Master 3S to left-handed users who were previously unable to use it fully.

To print the left-handed shell, it's essential to orient the hardware inside to fit the new design. The internal components must be mounted in the right spot for proper functionality. When it comes to the materials, stronger options like ABS or PETG are recommended over PLA if you plan to use the printed shell daily.

The layer texture produced by the printer should also be considered when finishing the print for a more polished design.

For those new to 3D printing, this project could serve as an introduction to the world of DIY hardware. When buying a new 3D printer, factors like build quality, print speed, and compatibility with various materials should be taken into account. If considering purchasing a 3D printer for this or similar projects, research the best 3D printers to find a suitable model.

It's important to note that this mod does not financially impact Logitech as lefties who want the left-handed version will still need to buy the original mouse. However, this is the only way for left-handed users to use the Logitech MX Master 3S until Logitech releases a left-handed version.
