Kleenex Hand Towels Box Holders

My very first 3D project. Used ABS, worked well. Used the larger 3M two-sided removable tabs to stick it to the wall. The brackets were made for the 60 1 ply Hand Towels box. Don't know if there are other sizes of boxes. I notice the angle of the boxes very a little. The angle of the brackets seems to be a good general match.
