Good quality,fast shipping

After my basic aluminum flexible coupler gave out I needed one asap. This was the only one I could find in stock in Houston. These are way superior to the basic aluminum ones.

This is a good coupler, transmits power, but will separate if stressed too far. I had this happen a number of times while I was adjusting my alignment. This is a good thing, as nothing gets bent or broken

This is my second set of these to upgrade to a second z Screw, the first set I ordered have been installed on my first printer for a little while now and they work great.
