This is a 40° mount for the Logitech Logicool wireless mouse ERGO M575. (The wireless mouse ERGO M575 is not included.) I made this myself to reduce the strain when using the mouse. (The item for sale is newly made.) ・In addition to the angle of the mouse itself, it has a 40° angle, which is close to the handshake angle. See photo 6. ・It is homemade with a 3D printer, and the material is PLA+, the color is black. ・The inclination is 40° and the weight is 40g (actual measurement). ・It was created with a density of 10%, so it should be fine for normal use, but please be aware that it is weak against twisting. ・The receiver and battery cover can be stored. You can turn the power on/off and switch the connection method through the center hole while it is attached to the mouse. ・Four 100-yen shop non-slip rubber pads are attached for non-slip purposes, so it is lightweight but stable. ・This is a 3D printed item, so please purchase with your understanding. If you have any requests for photos from different angles or any questions, please leave a comment.
