update: added my own 1.1 top design as well :-) (see last picture)
BOM:
2pcs 250mm rails (mgn12h Z2 medium preload)
IMPORTANT…. ask for Z2 medium preload when you order

M3 and t-nuts for the rails
3pcs M5x12 (for the new x-plate
1pcs milled X-plate (7mm thick)

DISCLAIMER… the ali plate is only 6mm thick on the AliExpress drawings
but some have received a 7mm plate
6mm can give some issues with leadscrew!
let me know and we can work it out.
I have provided the step file of the plate if you want to mill it your self
(DO NOT PRINT THIS IN PLASTIC)
PS. the 2 top parts need to be printed as well (ONLY FOR THE 1.1)
assembly tips:
- Replace the printed parts on top of Z extrusion (only on 1.1)
- if printer is assembled. remove old rail and x-plate
- mount both rails and X-plate loosely(not to the X extrusion)
- adjust 1 rail so it's parallel to the Z extrusion and tighten it
- move X-plate up and down a few times (2nd rail will self align)
- tighten 2nd rail
- hold the 2 carriages up against the top part (to align them)
- tighten the x-plate the the 2 carriages
- mount the x-extrusion to the x-plate loosely
- align the x-extrusion (the 2x soda can trick) and tighten the 3 M5 screws
all this can be done while the rest of the printer is full assembled
