Gridfinity 1X1 holder for three cables. Intended for use with USB charging cables, but can hold two cables up to 3ft long very easily. Print as many as you need, for the amount of cables you have. Cables are stored nicely vertically, making them easy to grab when needed. Includes magnet holes, but no screw holes. 

Print Gridfinity base down, any layer height, support not needed.
