This is a tilt stand for the Logitech MX Ergo / Ergo S. It was 3D printed and tilts the mouse 30° to the right with a slight forward tilt. The top surface is a steel plate. Neodymium magnets are attached to the bottom. The trackball body and the base plate are firmly secured together. ◼︎ Regarding the forward tilt: The advantage is that the hypothenar eminence (the fleshy part of the palm on the little finger side) touches the desk, allowing for a natural grip. With a simple right tilt, the height didn't match, and an armrest was necessary, so I 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 40° tilt) Please consider it if you're interested.
