    Lead Screw

    Posted by Matthew on Aug 27th 2022

    I purchased this for a DIY CNC project machine. It arrived faster then anticipated and the packaging was very nicely done. I haven't used the product yet but close inspection gives away that it surpasses similar products via. Amazon. It's worth noting that this is the same size shaft that my Ender 3 uses. Of course I bought a considerably longer one, but same diameter/threads. It would be nice if there was a ball bearing version in similar size.

    Excellent Quality

    Posted by Walter Carper on May 24th 2021

    This leadscrew works well with the nut blocks sold by openbuilds, but be aware that it is not 100% compatible with other brands that you might find on Amazon. Though the specs are the same, this is slightly smaller and will not work with non compatible nut blocks sold elsewhere. However, quality is excellent and performance is superior to no-name amazon brands.
