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

The belt is within spec of the original belt I replaced. Original was metal wire reinforced, this belt is Fiberglas reinforced and just a hair thicker which makes it stronger. The bulk belting material is just that, no metal sleeves for installation you will need to reuse your old ones and clamp them on to the belt ends or buy new ones listed on the same page as the belting. This is not a “kit”, you cut the belt to length and add the metal clips to attach the belt! I used this belting on a Creality CR-10 3D printer and it fit just like the factory belt which broke after 5 years of constant use. I expect this material to last about the same. Amazon also sells a “kit” for the Creality Cr-10 which includes two belts X and Z axis, pre cut and clamped with the metal clips for those who do not wish to make up their own set from scratch. I will repurchase this belting if it wears out down the road. Order was easy, mail was fast, printer is back in action. I am a “happy customer”

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.

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.

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

Ive tried a lot of generic gt2 belts. This one is stiffer than some but definitely fiberglass based so it can last a while in a 3D printer. But after less than one hundred hours print time every run of this stuff has failed. I now recommend triangle labs as the only gt2 generic that is reliable. It costs about 3x as much but lasts more than 10x longer under higher tensions. And of course you have to get that elsewhere on ali.

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.

Nice

Been using this on a CoreXY printer for many months now and this belt has not stretched. It fit all the pulleys and gears perfectly and therefore moves quietly. The loudest noise is the power supply fan! Only ended up using half of it on my printer that is 21x20 OD.

Just the fix we were looking for. Not a bad price quick shipping.

The carriage plate belt on my Glowforge had become loose so I purchased this to replace it. I had to guess how long to cut it and ended up shortening it twice before it seemed to have the correct tension. Works perfect.
