I found it easier to organize cables by adding a hook to the clamp. I didn't modify the stl's, I recreated the clamp using Fusion 360. I think I used more relaxed tolerances than the original design.
The samples were printed on a Prusa MK3s, using PLA filament. The stl file was sliced using PrusaSlicer 2.5 set to use the new Arachne engine at 0.30mm layer hight DRAFT mode.
The author remixed this model.
