This was a collection/combination of different parts across thingiverse with some modifications to allow proper z stop adjustment and cable management.
Ive added a file that now has a hole for accessing the foot screw
supports were only needed on the motor mount
There were ups and downs to each part used.
The original motor mount side of the chain by ryks allowed proper chain movement however reduced max Z height so i added clearance.
The cap on the screw for z adjustment by Meermeneer wasn't working for me.
And the extruder end of the chain by Starwhooper mounts better.
