Review on Enhanced Power Transmission Products with Threaded Backlash Spring - Sunhokey by Dustin Keller

I purchased these nuts after reading a review titled "Modification Required to Work with Ender 3". Based on this review, it appeared to be just a matter of removing the material from one side of the nut's mounting flange. I have a CNC machine so that's not a problem. The problem is that the distance between the centers of the mounting holes in the play nut flange does not match the distance between the holes on the Ender 3 Pro's Z-axis bracket. Too narrow. A possible solution would be to enlarge the holes in the play nut flange. This would leave very little material around the edges of the mounting holes, so I decided not to go that route.
