CR-10 cable guide

A Remix of Nicolas65’s cable management (https://www.thingiverse.com/thing:2527188) with a few minor improvements:
- wide enough now to put ABL-Sensor cable inside as well
- use wider zip ties
- reduced the number of zip ties
- added a small side bit to accommodate x-axis motor cables.

Any questions or suggestions, leave a comment.
Happy printing.
