ServoClass(TM) couplings are for servomotor and precision motion-control applications and feature zero-backlash flexible metal discs and keyless clamp-type mounting hubs. The couplings offer high torsional stiffness and low inertia to avoid system resonance. The couplings' flexible design also accommodates higher torque, high speed, and high misalignment and require no maintenance. ServoClass couplings are available in six sizes in torque ranges from 8.84 to 221 inches-lb.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
