Arcade Spinner
thingiverse
These are 3D printable components that can be utilized to create this extremely nice arcade spinner utilizing mostly 3D printed parts. I substituted the main 1/4"-20 screw with a 5/16"-18 threaded rod so that I could use leftover Prusa Mendel parts to make the spinner. This design employs a stack of 5/16" fender washers, a ~4" length of 5/16"-18 threaded rod, six 5/16"-18 nuts, two 5/16" lock washers, four 5/16" standard washers, and one 608ZZ skate bearing. It also employs the 6-32 screws and the metal plates discussed in the link above, as well as the mouse components. With all of the leftover printer parts I had lying around, and the fact that I already had an old mouse I could utilize, this only cost me approximately $8 to create.
