Scroll Wheel Button Extender for Logitech MX Master 3S – Perfect for CAD Users

The Logitech MX Master 3S is a fantastic mouse, but if you use it for CAD work, you may have noticed that the scroll wheel can be difficult to press.

To solve this, I designed a simple yet effective button extender for the small center button that makes it much easier to activate without shifting your grip. With this extender in place, you can press down naturally while your finger is on the scroll wheel.
In the Logi Options + software you can assign this button as Middle button

Use some thin dual sided tape or hot glue to fix the button extender
