I just needed something to manage hanging cables under my desk.
I hope this could be useful for someone else.
I used a simple double stick tape for fixing.
Note: print with flat surface facing towards hot-bed. In this way, the surface will result smooth enough to allow tape adhesion.
I suggest to use supports and print in provided XYZ orientation (see print preview).
In this way, the flat face, where tape should be attached, will result smooth enough to allow adherence.
