A cable organiser to clear the mess of loose cables on/under/beside your desk or anywhere they appear. Fix with two screws through the holes in the body of the organiser.
Print the flat, wide end to the print bed and no supports are needed. Any material should work - mine is made of recycled black ABS by Refil (get it in Finland from filamall.fi). Resolution is, up to you, this is not a piece of art but hidden under the table with the cables. You might want to use more than 20% of infill depending the weight and tension you're planning to place on it.
This is modeled with Autodesk Fusion 360 and the .f3d file is attached for anyone wishing to work on it in Fusion. A STEP file is attached for anyone with some other compatible 3D modeler.
