3D Printing GT2 Timing Belt, Zeelo 10 Meters (32.8ft) GT2 Open Timing Belt 2mm Pitch 6mm Width Rubber Fiberglass Fit for RepRap Prusa Mendel Rostock CR-10 Ender 3 3D Printers - Black

Do not order. They shipped 5 m only not 10.

The belt seems to be really low quality. About an inch portion of the belt stretched after using it on my ender3 for about a month.

Used this to replace the belts in my voron. Worked great for 1 day. Then I checked the tension because they typically need to be tightened a little more after theyre broken in. Belts were more loose than I had strung them before tensioning at all. Figured they probably just stretched more than Im used to and tightened them up again. Checked on them a couple days later and they were loose again. Decided to string one of my old belts on and leave one of these. Upon trying to get this tightened I noticed I could just keep pulling and pulling and these would just keep getting loose within a few minutes. After a half hour or so of tightening and waiting then retightening this is what I found (pic). Never again would I buy these belts. Ever.

I have several 3D printers of different brands and models printing 24/7. I 3D print free ICUshieldMN face shields. These belts are great. They fit all the different printers I have and hold up great as any belt I have used. In my picture you can see what a normal belt (left) and a stretched out used belt (right) looks like after 5 months of 24/7 use.

Belt failed inside a 50c chamber for only 300+ hours, a good quality belt should last 10x longer

Decent price. Functions as expected

Kit was perfect for a 6050 build im doing. I had no issues with the parts and they were packaged well! Rollers are nice and sturdy. I recommend this for a DIY build aluminum extrusion frame.

No stretch at all! You can get your belts so tight without stressing the steppers! Glad i picked this brand!

If youre working with GT2 belt, this kit is really handy. I never figured out their intention for the springs, but the belt, idler and pulley got my project going when I could not get the parts I originally ordered from Shanghai. The pulleys are nicely made, and it includes a lot of belt.

I used to this on the robotics on a long-arm machine and it works great
