Interference Filter Cable Clip Thingy

I own a Thinkpad with dockingstation that stands on my table. Sadly the ferrite core interferance filter attached to the cable always gets caught on the table's edge when I pull my laptop closer resulting in a disconnected charging cable...

Enter this thing.

It is an easy cone shape to be glued to the cable to make it getting caught on the table a thing of the past.

I modeled it in OpenSCAD so that you can adjust the dimensions of it to fit your own needs.

This is my first model mad
