Double cable clip for 6 mm OD cable (9AWG)

I wanted to keep the wiring on my solar install tidy. I made a cable clip for a pair of cables (negative and positive) with a 6 mm outer diameter.

The clips use simple nylon zip ties to constrain the cables to the guide, and a small wood screw (hole is 3.9 mm ID countersunk). I have attached some pictures where I have used them on my DC isolator. My cables are 6mm^2 (9 AWG) flexible silicone cables with an outer diameter of 6 mm.

I have attached the FreeCAD model for those who are interested. I hope it helps someone with their .cable management :-)
