Many modern gaming mice designs are physically symmetrical - this makes it easy for both left and right-handed users to pick up and use them. Companies like Logitech, however, have stepped away from this trend by creating ergonomic designs like the one for the popular Logitech MX Master 3S. This mouse is made with exclusively right-handed users in mind, with some buttons oriented to one side, where the thumb would be positioned. Not happy with this dextrous-exclusivity, maker Matthias Deblaiser decided to reverse the design and 3D print a version for left-handed users.
The right-handed layout of the mouse extends to much more than just its shape. It's not enough to reverse the housing, there are internal components that must be mounted in the right spot so they'll work properly. The left-handed MX Master 3S takes the internal hardware into account and allows for left-handed users to use the mouse fully as intended.
