Oldham Coupler: A Simple yet Effective Solution The Oldham coupler is a straightforward design that delivers impressive functionality with minimal components. At its core, it's just one essential part - a screw (M4x25mm in my case) that serves as the foundation. A T-nut (M4 in my case) complements the screw perfectly, providing additional support and stability. The T-nut is a critical component that helps to distribute forces evenly and maintain precision. One nut, specifically a blind nut or similar (M4 in my case), rounds out the coupler's design. This essential part ensures secure connections and prevents unwanted movement. The key to the Oldham coupler's success lies in its simplicity - it requires only one point of contact between the trapezoidal screw and the 2040 profile.
