We play a lot of games and sometimes it becomes difficult to keep track of the score sheets. We wanted to group the scoresheets by the number of players. These paperclips, now with numbers 1 through 9, allow for a quick find of the appropriate stack of sheets desired.
I used Tinkercad to add the numbers to the existing model. Origin model from https://www.printables.com/model/46589-paper-clip
