Now that I've completed core assembly, its time to obsess over cable routing.
I found a great collection of 2020 snap-ons.
I started by routing the right hand z-motor wires through the t-slot and holding it place with "2020_90Grad_cliped_2st.stl"
2 more on the inside keep everything tucked away.
1 more toward the left hand z-motor bring the 2 wire bundles together.
Using the same clip, I routed the y-motor and end stop wires along the bottom of the y-carriage. One on the inside near the motor and another on the outside near the RAMPS board.
I used the "2020_90Grad_side-ring-big.stl" to route the power cables under the y-carriage.
The rest is still a work in progress. I'll keep experimenting with the remaining clips until I find an orientation that I like.
