Update* 04/26/2021: I added chain connectors for the direct drive if your using my design Direct Drive make sure to use chain connector hotend with Direct Drive and chain connector X with Direct Drive..

Update2* 04/26/2021: added connector for the board box enclosure. same as the picture of my 3D printer

this is drag chain / cable chain for anycubic mega zero v1 and v2
it required no additional screws to install
you will need one zip-tie to mount the Hotend connector
I used 20 chain link for the X and 20 for the Z I didn't make any connector for the bed as I have a DIY bed for mega zero v1 and I have no idea how is the wiring orientation on the V2
for x mount, use 3 screws from the X motor

the base mount you need to remove the 2 frame screws and slid the mount in the V slots then reinstall the 2 screws back in place

update added chain connector for the hotend V2
it has support holder to keep the chain suspended....
also fixed some errors in the other connectors...

if you notice any mistakes that need fix let me know in the comments

UPDATE1: fixed some mistakes on the X connector
UPDATE2: added screenshots for orientation the way I slice them in prusaslicer

my printing setting
I use PETG as its stronger then PLA and also more flexible but however you can use whatever filament you like
print the chain link separately without support, brim is optional:
for all connectors:
PTEG Infill:20~30%, or PLA infill: 60~90%. support on build plate only, brim
