Rook 2020 MK1 Kirigami Bed Revised

This mod will get MK2 update soon-ish. It'll require some extra HW and Z motor mount to be reprinted.

Extra BOM:

1. Kirigami bed
2. 2x M3x5x4 heat inserts
3. 4x M2x20mm screws
4. 4x M3x8mm screws
5. 2x M3 nuts
6. 2x M2 4mm heat inserts or 2x M2 nuts (both work great)
7. 2x CNC Rod holders (MK2, e.g. https://www.aliexpress.com/item/1005004286446920.html?spm=a2g0o.order_list.order_list_main.17.70111802ORLPwO)
8. 1x M5x80mm rod (MK2)
    

There are 2 versions of adapter depending on how far to front you want your bed to be placed. Normal version is positioned relatively to MK0 Rook bed position, it's 5mm closer to the back of printer, while +5mm version let's you put your way further to front letting you use some extra space for longer toolhead of auto Z.

There are also 2 versions of Rod Holders. If your rods are super straight you mind find luck with combined holders (I'm using those), but if you want more flexibility you can use splitted ones or alternatively, use combined at the bottom and splitted on top. You're free to choose.

How to build:

1.  Insert all heat inserts and/or nuts to adapter and endstop hitter
2. If you want to mount endstop hitter to the right of stealthwire guide mount, do this before mounting adapter, it would be weay easier
3. Attach adapter using M3x8mm screws
4. Insert bearings to clamping holes
5. Insert M2x20mm screws to leftmost and rightmost M2 holes of kirigami bed (linear rails holes) and screw it just for fixing in place, don't tighten for now
6. Attach bottom rod holder/holders to aluminium extrusion
7. Insert rods
8. Insert bed onto rods
9. Attach top rod holder(s)
10. Align bearings by moving bed to top, then with some force to bottom
11. Tighten M2x20mm screws that hold bearings
