The sanding jig allows wood workers to make repeatable round overs at your bench top disk sander. It can be made to the size you need for your project. A very common use is rounding over the corners of the base or lid that is fitted to small desktop boxes when the trench holding these has been cut on the router table with a trenching bit with a bearing on top, a technique regularly demonstrated and recommended on the Gifkins Dovetail YouTube channel. The 11mm jig is perfect for such purposes.
