KeeYees 5M GT2 Timing Belt 6mm Width + 20 Teeth 5mm Bore Belt Pulley Wheel + Idler + Tensioner Spring Torsion + Gear Clamp Mount Block with Allen Wrench for 3D Printer RepRap

Very well made. Works as expected. Absolute pain in the butt to change out, but that says more about the printer than the belts.

Great little kit for a stepoer motor project that I did. The value was good, and it functioned perfectly. Everything was accurate and well made. I would recommend to a friend.

My LulzBot Mini now being about 5 years old really needed new belts. The old belts by Gates (a brand I trust and use in my vehicles) kept stretching out no matter how much I'd tighten them. This new belt is stiffer, smoother, quieter, and so far has been keeping tension really well. These might just break if too tight vs the Gates that seemed to stretch indefinitely. So depending on your needs you may want to take this into consideration. Strength seems less, but for this application that was OK as the other benefits were substantial. I haven't used the accessories this belt shipped with, but I plan to use them for another project. Also there's plenty of extra belt left over, I only used maybe a third for both my X and Y axis.

The Idler pulleys are too large for my printer (Monoprice Select mini V2), but otherwise everything else fits well. The standard pulley works great on the X and Y axis of the printer, holding tightly. Remember to adjust your E-steps though. use the calculator on prusha's website to calcuate the number needed. I got 80 for my particular setup, altough you would have to adjust for your particular setup. Just put in "M92 X80", and then "M500" and I was good to go. The Belt itself is stronger than the old one (6mm belts WILL fit on the stock gears, I tried it.) and will be much more stronger. it was kind of a pain to replace the X axis belt (loop), but it does work. You just need a lot of zip ties to hold it in place. This will go a long way in keeping my only printer in operation!

Muy bueno

With this belt material and some compatible pulleys, I was able to make my own custom pen roller for my lazer engraving device.

It comes with a variety of pieces I was able to use for the different needs I had for it. It's really long so I have a ton left for future projects. More gears can also be 3d printed so definitely worth it

This product is pretty decent. The belts don't have any reinforcement in them and the pulleys scratch pretty easily. Its not the best quality but for the money its decent.

product as advertised

I didn't need the belt tensioners or clamps for my application, so I can't comment on those. But the belt itself, the motor pulleys and idlers work great.

I needed a short loop of this belt, and followed an online tutorial to join two ends together with a bit of ribbon and some crazy glue. The resulting joint was pretty stiff and didn't go around the pully super well, but was surprisingly robust when I tried to pull it apart once I was done.

Didn’t use for 3D printer used for custom application but still great quality works minT

Looks great so far, havent used it yet. pretty sure it will get the job done !
