The base model was good, but I kept on having breakage due to some weak points.

Physical Changes:

• Reinforced tabs for holding cords on both the links and the cold end.
• Added large filets to links to allow movement both ways. This was necessary because during the homing the first and second links would collide with the frame causing the first cable to pop off the hotend mount. The filets allow movements but don't pinch the cables.
• Redesigned the male "balls" for the link connection. This produced a more consistent print as well as removed a lot of play in the links while still allowing movement and ease of installation and removal.
• Added extra supports to the hotend where it mounts onto the roller assembly.
• Strengthened all the parts that take any type of pressure by either increasing thickness and or adding fillets or chamfers to eliminate 90-degree angles that are likely to cause breakage during installation.
• Added general filets and/or chamfers to cable links and hotend to increase ease of installation as well as protect cables from wear.
• Created 3 different link lengths. Regular, short and extra short. This allows easier customization of length. Due to the ability for the whole cable link length to flex in both directions this is pretty flexible (pun intended) on how long you want it to be. As long as you have the minimum amount to make it to your far X-Axis position you should be good. Adding more shouldn't hurt.

Model Topography Changes:

• Made sure all surfaces mate to each other.
• Made sure all rounded areas had completed solid faces instead of a group of vertices and included step files which metadata that stl's do not.

Why this matters:

You will now be able to easily remix any part you need or adjust dimensions for any part to be looser or tighter. You can easily add, remove or modify any of the faces as well as increase or decrease any fillets or chamfers. You just need to simply import the step into any cad program and get to work!

If you notice any issues or places where I can learn (I'm still only a year in of self-taught CAD) please share :)

Enjoy! :D
