Ender 3 cable clip

Clip to help organize cables on the Ender 3.
Several attempted improvements/changes to the original. Original clip had the following issues for me:
- When clipped in, it was loose, wobbled around, wouldn't stay straight.
- Extremely difficult to remove. I gouged the paint on the extrusions trying to remove.
- There was no extra space for additional cables, such as a USB cable for Octopi.

This modified design attempts improvements in those areas.
