Screw Crank
thingiverse
This is my customized adaptation of the Wimshurst Machine's Crank, based on the original design found at http://www.thingiverse.com/thing:178321. I am thankful to DieKatzchen for creating the initial code designed for fitting a nut; my slightly altered code enables use with a screw secured by a nut. The default settings and 3D model are specifically tailored for an M4 screw and nut.
