Ender 3 cable chains

Cable chains for Ender 3, remixed from two things.

### What is changed

- Extruder's hotend mount shifted to the right, so the cable bends less.
- Bed mount with grooves. It allows you to screw the mount close to the bed, no backlash.
- Chain link without useless overhangs. Walls are stronger.
- Bed spring compensator. It's my addition, not a remix.

**Update 09.04.2020**

Added _hydra chain head.stl_ for the [Hydra Fan Duct & Tool Change System](https://www.thingiverse.com/thing:4062242)

You don't need this if you're using the stock Ender 3 cooling system.
