5 Meter 6mm Width GT2 Timing Belt for Reprap Delta 3D Printer Kossel Rostock

Belt is flexible enoughm yet very resistant to stretch. Perfect quality and works great.

Bought this for my Tronxy X5S corexy 3d printer. This was enough for both belts on this fairly big printer (330x330mm print bed) with a negligible scrap left over.Seems pretty good stuff. Is certainly fiber reinforced which should not stretch like the steel reinforced belts that came with the kit, and the price was right.

This belt is steel reinforced. I ordered this one because it was advertised as fiberglass reinforced to replace steel belts that broke after a very short time. I'm going to use it and just reduce tension.

Got this for my Anet A8 (Prusia i3) 3D printer to add belt tensioners. I cut the previous belts just long enough without the extra space needed for the tensioner. The belt fits perfectly into the existing gears and is even more flexible than the belts provided. The length is long enough to replace all my belts several times.

Installed on my 3D printer, and only made it through 1 print before a belt snapped.

Really good belt that worked great on a Reprapguru i3 v2 3d printer. I will definitely buy again when needed. Had enough belt left over to replace again if needed.

Pro: Much better than the cheap plastic belt that came with my 3d printer and removed some slack and is easier to work with.Con: the teeth aren't bad, just would have liked for them to be a bit stiffer, as the belt can still slip if bed is obstructed.

So far this has been an improvment over my Anet A8's original belts. These are much more flexible and have a nicer, rubbery feel. I was also able to install 3d printed belt tensioner with these belts. I have seen a 10-20% increase in print quality.
