Hey Jussi,

they don’t say the spindle diameter, or did I miss that? The diameters that will work on the Onefinity are 65 mm, or 80 mm with [80 mm spindle mount](https://www.onefinitycnc.com/product-page/80mm-spindle-mount). Unfortunately the spindle clamp that is shown cannot be used on the Onefinity, except if you replace the entire Z assembly with an [Universal Z assembly](https://forum.onefinitycnc.com/t/universal-z-axis-assembly/4415).
