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 securely fixed 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 front became too high, and my thumb couldn't reach, so I made adjustments. The feel of the "ball" and "thumb," and the feel of the "forward button" and "index finger" are about the same as the standard 20°, so you can use it without any discomfort, maintaining the original feel. ◼︎ 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. (40° and 50° versions are also available) Please consider it if you're interested.
