Screwless Z-axis cable chain mount

NG_Design's cable chain mount remixed with Tobi0892's cable chain link to allow compatibility between the Tobi0892's cable chain design and NG_Design's screwless mount.

Unfortunately a small support is needed under the chain attachment area. I did the remix through Tinkercad quickly and for the first time without any background in using that program, therefore the bottom of that area is not flush with the rest of the assembly.

Reason for this remix:
The reason I did this remix is that I was in the process of adding cable chains to my printer using Tobi0892's files, but realised the bottom screws of the Z-Axis motor has to be removed to mount their Z_axis_stepper_connector.stl (at least that's what appears to be required).
I didn't want to risk any potential realignment issues on the motor assembly due to screw removal, therefore pulled out NG_Design's mount and replaced the link attachment with Tobi0892's design.

Obviously, wouldn't have to have done this if I used NG_Des
