This is a tilt stand for the Logitech MX Ergo / Ergo S. It was 3D printed and tilts the mouse 40° to the right with a slight forward tilt. ◼︎ Structure: The top surface is a steel plate. Neodymium magnets are attached to the bottom. The trackball body and the base plate are firmly fixed together. ◼︎ Forward Tilt: The design is such that the little finger side is the lowest, allowing for a natural grip with your wrist resting on the desk. With a simple right tilt, the height wouldn't be right, and an armrest would be needed, so I've made adjustments. ◼︎ What you will receive: ・Tilt stand body ・Stick for removing the ball That's all. I've been using this myself through trial and error, so I think it will be helpful. (Also available in 30° tilt) Please consider it if you're interested.
