Yowming 10 pcs 3D Printer Big openbuilds Plastic Pulley Passive Round Wheel with Bearing Idler Pulley Gear Perlin Wheel Driven Wheel

I used it for my cr-10 and they work just fine. Smooth and steady.

Several of the wheels were not perfectly even and would cause the bed to raise and lower a mm or two up and down as they traveled. This made them completely useless.

I have purchased the mini wheels here on Amazon for my home built 3D printer and could not be happier. I got these for my large 3D printer/CNC router hybrid and once again I'm not disappointed. Work just as good as the other guys at a fraction of the price. Will be buying more.

Worked great on my tevo tornado
