Minimalistic cable channel

Channels can be put next to each other and/or form a single straight line. There are two holes for screws, but can be also glued onto the surface. The cable it self is simply pushed into the dent which is exact snap-in size so that it holds pretty tight.

STL is for 7.7mm power cable, but parametric FreeCAD file also included to generate other ones for different diameters.
