Railcore XRAT (X Rail Alignment Tool)

NOTE: This thing has been semi-superseded by the [XRAT 2.0](https://www.thingiverse.com/thing:4435803). The old design still works fine, but if you're working on a new build, I would suggest considering the 2.0. That said, it is a slightly harder print and does require additional hardware, so I'm leaving the original design available for those that would prefer it.

This is a screw-driven adjustment tool for the X linear rails of the Railcore II.

End caps are placed over the ends of each X
