Getting there. God, that was a lot of absolutely awful work. Aligning these MGN12 rails on the Y- and Z-Axis and getting them parallel and flat was an absolute nightmare. But it's smooth now.

Now comes the scary part: Ripping apart the old printer to harvest the motor and hot-end. There's no way back should I have forgotten to print something.

Oh lol, the X-Axis rail needs to go on top instead of the front. Easy fix though as it is just a single rail that doesn't need alignment to another one.
