My earlier design for a Kossel cable tidy was designed to be screwed to an extrusion, then the cable slipped under the loops. However, it was sometimes difficult to slip the cable through the gap at the side of the loop, and it didn't grip the cable. So I designed this two-part one, which grips the cable between the two parts.
Use M3x12mm cap head screw and slot nuts to attach them to extrusions.
