Creality Ender 3 V3 SE / KE 10mm Rod Upgrade

I'm very unhappy with the product. I have removed it from my machine and returned to the factory rails.

rods are slightly too small in diameter

as in the title the rods are a touch too small in diameter which allows play in the bearings... bought the same size bearing from two different manufactors and same thing... machine prints better with the 8mm rods for now so ill have to stick with that

Cut down on vibration so I can print at higher speeds
