M570 Tilt Stand 40° This is a stand specifically for the Logitech wireless trackball mouse M570. It is used by removing the back cover. The stand's protrusions fit into the place where the receiver is stored, so the mouse won't slip. There's also a cavity to store the cover, etc. There are non-slip pads on the bottom. While the MX ERGO has a 20° tilt, this product has a 40° tilt. Personally, this angle is the best. [Product Overview] Top Angle: 40° Color: Black Material: Plastic 3D printed product [Other Notes] M570 is not included. Initial defects will be exchanged. The surface texture does not have a high-class feel. There are layer lines unique to 3D printers.
