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

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

Index

You can use an index image, but it was taken from the original thing and doesn't match with my names.

My recomendation

You'll spend a lot of time to printing all chain links, and it will turned out they not so required. But, some parts turned really useful:

1. whole X axis, hotend cable part. It allows to unbind PTFE tube from cables.
2. bed corner.stl (without cover!) - securely fixed table cables.
3. bed spring compensator.stl. It will setup all springs to the same height; easier to calibrate the table.

That's all what is "good to have", but you can print all chains of course :)
