generative z slider for railcore mini with lm10uu (2 versions)

There are two versions available a 19.00 mm and a 19.05mm bore.  Try the 19.00mm bore first and if you're able to press the bearings in (they will be tight as this is likely an interference with how printers work) go with that if it is simply too tight considering calibrating flow rate or try the 19.05mm bore version.  I have an alternate version i will also upload that prints even easier and is laterally stiffer.
