This a spinner with buttons you can press to relieve stress. There are five 5 buttons one for each finger and there's small notch in the back to spin the model. Or if you are feeling adventurous, you can take the 2 hubs separately, tie a string and make yoyo. I primarily used my Bambu Lab P1P to print this. You will need to print two plates the buttons, and hubs on first plate. And the two parts of the center ring that hold the buttons in place on the 2nd plate. You can print it in 2 colors or all in one or on 3.
