Tilt stand for ELECOM Trackball Mouse DEFT PRO (M-DPT1MRBK) 15° + 15° + 10° + 5° (Total 45°) *This is a sale of the tilt stand only. Mouse is not included. Reduces wrist fatigue and pain. Adjustable from 15° to 45° in 5° increments. By rotating the tilt angle, you can distribute the areas that are burdened. Receiver storage pocket included. Silicone rubber on the back. (Silicone rubber can be stacked without removing it) If you have a set square, we recommend that you imagine the feel of using it by placing the 30° and 45° parts under the mouse, parallel to the battery cover line, before purchasing. (In my case, I felt that a higher wrist rest was necessary, so I cut a 100-yen wrist rest mouse pad and adjusted the height to use it) Especially when using it around 45°, when moving the cursor greatly to the right, the trackball may behave in a way that it slightly comes off the support ball when your finger leaves the trackball. Some people may be concerned about this, so we hope you will check it using the method above. This is a handmade product made with a 3D printer. The main material is PLA resin, and please be aware that it may deform if the room temperature exceeds 60°C. We have confirmed that it does not affect the use, but please understand that layer marks and fine scratches may occur during the manufacturing process.
