All Started with this project: https://www.thingiverse.com/thing:4258451
Longer printers are pretty close to Creality as they use same opensource project, but all dimensions and some of the construction is different so I had to redesign everything from the ground up with the correct dimensions.
I ended upgrading all Axis to linear rails MGN12, dual Z motor. In the process I also switched to Direct Drive with some parts I had from before (works with original hotend and extruder too)

Attached is BOM for all the parts from Aliexpress (price in EUR).
You will need also some M3 and M5 mounting hardware
Included Z axis mounting blocks, right gantry assembly backplate both for single and dual motor (Longer do not use one), Y-axis endstop modification to go over rail for proper alignment.
Modified tool for Z-Axis vertical alignment as my gantry sits higher - original here: https://www.thingiverse.com/thing:4320411
