Tri Fidget Spinner With 3 M8 Nuts

thingiverse

Visit http://fidgetexpert.com for more projects and guides. A tri-fidget spinner I designed in 123D Design uses one skateboard bearing paired with three hex M8 nuts. Note: Be cautious! From the start, the sockets for the hex nuts are slightly too small, so use a lighter to heat them up, then push the nuts through for a snug fit. This will prevent the nuts from flying out of their sockets. I suggest printing a cap for the ball bearing as well.
