Here are the items you requested. This is for the person named in the title, so I will not do business with anyone else. This is a tilt stand for the Logitech MX Ergo / Ergo S. It was produced with a 3D printer. ◼︎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. ◼︎What will be sent. ・Stand body ・Stick for removing the ball ◼︎About forward tilt. The advantage is that the hypothenar eminence touches the desk, allowing for a natural grip. With a simple right tilt, the height comes forward, and my thumb could no longer 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, just as you are used to. That's all. I've been using this myself through trial and error, so I think it will be helpful. (There is also a 30° version.) Please consider it if you like.
