+# Top Corner Cable Hide/Cover (LED Wires)
+Designed to hide cables that are running around the top corners of 2.4 extrusions behind the z idlers.
+
+They are large enough to fit 3 pin microfit connectors.
+
+There maybe some small loss in z. Don't forget to check your clearances after installing.
+
+ **Pro tip: It may take some fiddling to get the wires to fit. You will know they are in place when it sits flush to the extrusions without wobbling. Also disable 'Thin Walls/Detect Thin walls' so the mounting ears print cleanly.**
+
+### Printing
+  * Default voron settings
+  * No supports needed
