伸缩键盘导轨 Retractable keyboard guide rail

2025/8/26更新：键盘固定收紧方式由原来的皮筋改为弹簧收紧。详见另一贴子Updated on August 26, 2025: The fixed tensioning method of the keyboard has been changed from the original rubber band to a spring. Please refer to the other post for details.https://www.crealitycloud.com/zh/model-detail/telescopic-keyboard-rail-tightening-modification?source=22我的键盘尺寸：键盘边沿厚度13mm，总厚度不超过25mm 如果您的键盘尺寸和我的不同，您可以试试通用款，只要键盘厚度不超过45mm导轨长度为210mm，我是采用竖直打印的，这样边沿强度更高，使用M3自攻螺丝固定。您可以使用双面胶临时固定，确定位置后再打孔固定。导轨尾部是用M3*6螺丝限位，防止脱出。The dimensions of my keyboard: The thickness of the keyboard edge is 13mm, and the total thickness does not exceed 25mm. If your keyboard dimensions are different from mine, you can try the universal model, as long as the keyboard thickness does not exceed 45mm.The length of the guide rail is 210mm. I printed it vertically, which makes the edge strength higher, and it is fixed with M3 self-tapping screws. You can use double-sided tape for temporary fixation, and then drill holes to fix it after confirming the position. The end of the guide rail is limited with M3*6 screws to prevent it from coming off.如果你不希望键盘拉出后向下倾斜，请不要用图2这款导轨。请使用另一款If you don't want the keyboard to tilt downward after being pulled out, please do not use the guide rail shown in Figure 2. Please use another model instead.如图1四个位置拧入m2*10的螺丝，增加强度最后，导轨安装好后，键盘放入托盘后，找两根橡皮筋（不超2MM粗）连接两端，夹紧键盘防止其掉落。您也可以使用细绳代替。如下图Screw M2*10 into the four positions as shown in Figure 1 to increase strength.Finally, after the guide rail is installed and the keyboard is placed in the tray, find two rubber bands (no thicker than 2mm) to connect both ends, clamping the keyboard to prevent it from falling. You can also use a string instead, as shown in the figure below.
