Dart hand spinner
thingiverse
I'm an educator, currently serving as a high school teacher, who created a hand spinner to instruct my students in making one by their own hands. To access the design files for this project, visit http://www.thingiverse.com/thing:2197998 or check out https://livingtechlearn.wordpress.com/2017/03/18/drawing-a-hand-spinner-with-onshape/. I had initially designed the spinner using a traditional method, but after learning about potential safety concerns at some schools, I opted to create a dart version instead. Please exercise caution when handling this device. The necessary components include a 4mm steel ball, one 608ZZ bearing, and three M35mm screws and nuts.
