SCStyle 5 Meters GT2 2mm Pitch 6mm Wide Timing Belt for 3D Printer CNC

Sort of a rubbery like belt. The type is the same used in many 3D printers. It stretches a little but not much. It can be cut to size. You will need to provide a method of locking down and securing each end and maintaining proper tension.Originally, I ordered a 5M length and used to fix up an older Monoprice Maker Select V2.1 3D printer and still had half of it available for spares. This belt has worked well for months on that printer.Lately I've built a Tronxy X5SA coreXY 3D printer. It has several meters of belts on it. So I purchased 2 of the 10M sizes. The parts kit that originally came with the printer provided some plastic belts which clearly weren't good and would stretched out too easily under stress. I knew after using the printer a bit that I had to regularly adjust belt tension tighter and tighter till I started to see stretch marks in the plastic belts provided. Replacing the belts on this printer is the number one upgrade to do to make it better.These belts have just enough rubber material that they give a bit during high torque direction changes but retain their length and tension well throughout the belt length. It seems they have something like fiberglass and rubber in the material. (Feels rubbery but has some sort of fiber-like material too that only gives a little bit.) On coreXY printers, belt tensioning and adjustment is very important as there are two opposing forces applying tension to the print head controlled by 2 long belts. These belts demonstrate good consistent pressure when used on this printer. And I'll still have one bag of 10M as spare if something goes wrong or for my other printers upgrades.These are much better that the plastic belts that sometimes come with 3D printers. Since I used these belts on another printer before and it's held up for months of heavy use, I would guess the longevity of the two new belts of double the size as the first purchase, will be still working months from now too on the corexy. The only reason I gave this product 4 stars was because they do seem to be a tiny bit thin (about 2mm thick with the teeth). But they so far have not had any problems related to that. If they don't hold up or if they last a year or so, I'll come back here and update this review.I recommend these belts for 3D printer use. I would also get the longer lengths (10M) as it gives you the leeway of having more on hand in case you end up cutting your belts too short by mistake or to use the excess as replacements if you damage them.

Very nice gt2 belt!Not that shiny plastic kind, this looks and feels like real rubber with reinforcing strands of fiberglass or something similar. Very nice and rugged feeling, no stretch, no wobble. Even sounds quieter!

Delivered on time, and appear to be exactly what they advertised. I have not used it yet, but it does appear to be good quality (e.g., newly manufactured, very flexible and strong). I have received older belts (from another supplier) that seemed to be dried out and ready to crack, and one did not 6 weeks after installing it. That is not the case with this belt.

So far this belt is performing great on my printrbot simple metal. Havent had any issues with it slipping, jumping position or snapping. And if something does happen, i have plenty of extra

Excellent, it worked fine with my Lulzbot Mini when I had to replace the belts on my X-Axis. I had plenty left, so I went ahead and also did my Y axis.

I used it on my TronXY X5S to replace their horrible plastic belts and the difference was night and day.

Saw some review photos where the edges of the belt were poorly trimmed. My belt came perfect and I'm very happy with it. I thought it would have fabric in it like a car belt, but it doesn't appear to. Belt is still super strong for its intended purpose.

It's a g2 belt, and it's good quality. Works great in my 3d printer, with lots to spare. Why are you smelling it?
