Generator Crank Handle V2.0

This is a fresh sheet of paper redesign of my original crank handle ( https://www.thingiverse.com/thing:3062521 )

Please see that project for more details. However, this is intended to go with this project (which is not mine) that I found online. See:
Not my project and not my video! Only this part is my original design.
