Ender 3 cable chains

thingiverse

Cable chains for Ender 3, remixed from two things. ### What is changed - The extruder's hotend mount has been shifted to the right, reducing cable bends. - A bed mount with grooves has been added, allowing you to screw the mount close to the bed with no backlash. - Chain links without useless overhangs have been created, resulting in stronger walls. - A bed spring compensator has been included, a feature I personally added. **Update 09.04.2020** The Hydra chain head.stl for the [Hydra Fan Duct & Tool Change System](https://www.thingiverse.com/thing:4062242) has been added. 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._ **Z axis** _14-16 chain links are needed._ link.stl link cover.stl _Mounting to the left leg at the top is required._ mount top.stl _Mounting in the area of the extruder, just hanging on the cable, no hooking to the frame is necessary._ x end.stl x end cover.stl **Y axis, bed** _15-16 chain links are needed._ link.stl link cover.stl _Mounting to the left leg from the side is required._ mount side.stl _Mounting to the bed is essential._ bed corner.stl bed corner cover.stl bed spring compensator.stl - 3 qty **X axis, hotend cable** _17 chain links are needed._ link.stl link cover.stl _Mounting to the extruder is necessary._ extruder side mount.stl x end cover.stl _Mounting and hotend side requires 40mm between the centers of the axes of the rollers._ hotend side mount.stl OR hydra chain head.stl // if you're using Hydra cooling system, see "Update 09.04.2020" above. ### My Recommendation You'll spend a lot of time printing all chain links, and it will turn out they are not so required. But, some parts turned really useful: 1. The whole **X axis, hotend cable** part allows you to unbind PTFE tube from cables. 2. bed corner.stl (without cover!) securely fixes table cables. 3. bed spring compensator.stl sets 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 :)
