Maker 3D prints left-handed Logitech MX Master 3S — fixes awkward button layout made for righties

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.

    Maybe they can fix the left mouse button. I had to RMA two mice already. Wouldn't recommend it for gaming, especially ones that have you pressing the left button like your life depends on it.

    Now they just need to fix the mouse's unusably high latency and bargain-basement polling rate.
    It's an expensive productivity mouse so laggy I couldn't even accurately move clips around in premiere with it. It feels as bad to use as a wireless mouse from dollar tree. Super disappointing.

    Mice are one area where I would recommend getting an off-brand or obscure brand.
    Especially if you're going to pull parts off of it.
    For mice, I would recommend Elecom, Perixx, Rapoo, ProtoArc (nulea), Anker (Delux), in no particular order.


    Stay away from Logitech and Razer peripherals. I wouldn't touch those with a 10ft pole.

    If you want premium gaming, Attack Shark, Glorious, etc.

    The Logitech MX Master 3S mouse and the G935 gaming headset are the only two Logitech hardware I have had problems with. The mouse really isn't an issue if I don't game with it (obviously wasn't designed for gaming), but the headset is a 100 Euro piece of crap.

    Also, I'm still using the Logitech Z-640 5.1 speakers I bought around 22 years ago. Plus, I've never had any issues with their keyboards or gaming mice.
