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

Used on my CNC machine. For the price I got 4x as much belt rather than going through the CNC manufacturer.

I guess this stuff has a shelf life of about 2 years. Its been stored in an air tight container with filament but I get about a week of use out of it and it breaks. Replace... use for a week.... And it breaks again causing layer shifts.

used this to replace belts on laser engraver, just cut to desired length.

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”

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!

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.

It missed all of the tensioner spring torsions

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