Wobble Fidget Spinner

thingiverse

This fidget spinner was designed to cater specifically to students with ADHD and autism who require a customized "fidget" tool to help them focus on the instruction and minimize distractions caused by traditional spinners. By unevenly weighting its arms, it provides additional sensory stimulation that may assist in keeping the student's attention on the task at hand. The spinner utilizes a standard 608ZZ 8x22x7 skate bearing available on Amazon at https://www.amazon.com/gp/product/B00NX1WBA0/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1, along with up to six 8mm chrome ball bearings accessible here: https://www.amazon.com/gp/product/B008M3584K/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1. Before super-gluing the skate bearing into the spinner and the two caps into the skate bearing, it is beneficial to sand both the outer and inner surfaces of the skate bearing. A noteworthy alternative method for mating the two caps without using glue can be found in a video by the 3D Printing Nerd at https://www.youtube.com/watch?v=EgOuvOLiwAM. Students created custom designs for their spinners, including the colors for each component, using Tinkercad as part of a lesson on 3D printing and modeling. They were able to choose from various options, such as the color of the plug that substituted for a ball bearing, which most students matched with the spinner's color. The PDF file includes the dimensions of the caps.
