Hey Tom,

if only the Onefinity Z assemblies had more travel! I liked our discussion in [this thread](https://forum.onefinitycnc.com/t/43mm-euro-spindle/15188/28) and imagine with a Z slider like this, that is able to protrude downwards beyond the lower end of the Z assembly, you would be able to keep the spindle center very close to the X carriage. But I would prefer to have two bearings per rail instead of one, and I fear that even the slightly higher Z-20 slider would not satisfy because its height is not enough for that.
