Clothesline Spreader Holder

I made this to hold the clothesline spreaders for my wife's Amish style clothesline. For those that don't know, an Amish clothesline has a pulley at both ends and you stand in one place to hang a garment and then feed the cable out to hang the next garment. Without the spreaders, the lower line sags badly. With the spreaders, the weight is shared between the upper and lower cables. We needed a place to store the spreaders as they take up a lot of room in the clothespin bucket, so I drew this up on Tinkercad. The screw holes are 5mm and the width of the rod for hanging the spreaders is 5mm.
