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

Replaced a broken belt on my 3d printer about a week ago. So far works well.

I accidentally stretched the belts on my delta printer and needed new ones. I ordered this, cut it to lengths, matched up the teeth to get exact lengths, then reinstalled the belts. And now my delta is working perfectly again with all three belts replaced using this. So yeah, works great!

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

I like it because as much do a lot of 3D prints your belts and pulleys will need to replace them

The belt I replaced with this is 1.4mm thick. This belt is 1.5mm thick. Thats not a huge difference, but it was enough to cause some interference I didnt have previously.

Replacement for my delta printer.

I bought a couple of sets of these to test out on a 3d printer build that I am doing. Everyone talks about getting Gates belts, but I tried these to see how they would do. Compared to Gates they are very low quality. They made some grinding noises on all of the pulleys. I thought it was misalignment issue. I swapped in Gates belts and all the noises went away.

Thank you

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.

I loved that it came neatly packaged and tightly rolled. It also looked and felt strong and clean. The only downside is that Ive had to replace the same belt 3 times now, from this same roll, because it stretches over a short time. I admit that I run my printer almost all the time, but I only had this for about 1.5 months and Im on my 3rd piece of it. Ive already checked that my motor and roller are not shifted apart, and the path it takes is clean and unobstructed. I did notice that since I print a lot in the center of the bed, and the parts are somewhat similar in size, that the spot where it started to stretch is the same spot, where it comes around the roller repetitively. I can only assume that this constant motion in one spot around the roller is whats causing it. But thats my experience with it. Ive since ordered and received a belt with a steel core to see if it can handle the prints Im doing, so it could just be me. And if it is, then this will at least let you know that while this belt looks, feels, and works great, it also has the potential to stretch under constant use and rapid movements in one spot.
