Drive-shaft Connector for Generic RC Servo 25T Spline ============================================ UPDATED 2017Jun28 ---------------------------- Ever had an RC Servo that you wanted to connect directly to a drive-shaft, not just a servo horn? You might have tried using a 3mm Carbon Fiber shaft and attaching it to an RC servo for some twisting action. Perhaps you need to connect an RC Servo to a customizable Spur Gear (0.5M) with ease. This design was created to solve that problem once and for all, The Dog3 is a clutch with three teeth, cleverly designed to attach securely to the 25T spline of your servo on one end. The other end connects seamlessly to another Dog3 dog-clutch, allowing you to customize the setup as needed. That second Dog3 can then connect directly to a 3mm shaft, leaving ample space in the rear tubular section for drilling and tapping 3mm grub-screw holes, giving you complete control over the grip on the shaft. The design files are fully parametric, giving you the freedom to customize them to your heart's content. Now included is a true 0.5M spur gear based on involute curves that can be customized at will, featuring a 25T spline on one side for added versatility. A dummy Generic SG90 9g Servo has been included to provide a size reference point. Additionally, a bearing support has been integrated into the design, capable of supporting the end of a 3mm shaft with an MR63 6x3x2.5 bearing.
