Direct replacement for our Ender 3 Max. These rollers assembled and worked perfectly.

customer service was friendly and very helpful!

I did a stupid thing. I went to Amazung and bought a ton of discount bearing wheels as replacements for my CR-10. That was a terrible idea. The discount wheels were similar, but dissimilar enough that there wasn't clearance when they were installed..so they fit, but just not perfectly. You you get what you pay for. They fit, perfectly, and turn. And now I have a functional printer again. Buy genuine parts, get genuine results. Thank God for 3D Printing Canada. Seriously.

Came relatively quick, and well packaged. Got us out of a bind!

awesome Quality and service

No flat spot and very smooth travel. I recomand
