Sandpaper holder. Print the first holder1 which is the start, you can print holder2 and put it together with holder 1 and if you need more holders you just print more of holder2 again. print the roll and pins, then glue the pins to the roller. You must use the split to keep the roll in place, probably meant if you have it hanging on the wall. I printed it with support, in the roller i already made the support so u dont need it for that, but remember to remove it before u try to put the pins in :)
