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

    5.0 out of 5 stars Great belt, replaced Gates brand with this and have been pleased.
    Reviewed in the United States on January 27, 2020
    Verified Purchase
    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.

    Reviewed in the United States on January 25, 2020
    Verified Purchase
    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!

    I ordered this for my Anet printer, which is very noisy, this belt paired with dampeners was a life saver, the printer still makes noise due to the cheap quality, but it definitely helped a lot when it comes to dampening the noise.

    3.0 out of 5 stars Didn't work for my application too well, but might be fine for yours.
    Reviewed in the United States on December 14, 2021
    Verified Purchase
    The belt seems fine dimensionally. The issue I had in my application is that the belt is a bit too "plastic like." Because of that it's friction with the pulleys is much lower and caused it to slip if the load on it increased just slightly. I ended up using a different "more rubbery" branded belt, and it worked fine. The pulleys that come with the belt were a nice addition, and I was able to incorporate them in my project. I did have a tensioner in my system, but the mating surface was around 100 degrees using one of the included pulleys, and that wasn't enough to work for me.

    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.

    Reviewed in Canada on January 26, 2021
    Verified Purchase
    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.
