It’s bigger than my original and so far it holds my z on my custom build.

They are built tough and surprisingly well machined for the price, and the 40mm length helps stabilize the axis of both shafts which is a common problem with 3D printers. Just make sure to check that your printer has sufficient clearance to accommodate the larger outer diameter and length. I just removed the lock washers to tuck in the screws for better clearance.

I'm going to give these four stars, they are well made and I'm sure would work nicely. However, for my application the 25mm diameter would just barely fit. I neglected to notice that the screws protrude from the 25mm circumference, causing the couplings not to fit my machine. Sent them back, but if you've got the room and need this style coupler I'm sure these are great.
