## Description

Connect this to that with a set-screw coupler. These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce binding effects. The way they're cut, they're a little springy in the X Y & Z linear axis but not in the rotational axis. That means that you won't get increased backlash - so they're suitable for precision CNC work. 

 This coupler will connect a 5mm diameter shaft to a 10mm diameter shaft. [A perfect add on for Adafruit's stepper motors](https://core-electronics.com.au/stepper-motor-200-steps-rev-12v-350ma.html). Comes with two sets of double set-screws (two per side) for secure attachment. You'll need a 2mm allen wrench to tighten/loosen the set-screws.
