Hand Crank generator Handle

Tim Station made a hand crank generator, but the crank of the generator was a bit to long for my taste. And it also needed an shoulder boult. 

I designed the crank to be a bit shorter so you don't need to move all over the place. The hole of the handle is a full threaded M10 hole wich holds an M10 allen boult with a tight grip. so this works perfect. 

the coupling on the gearwheel is a bit tight, but it works grate with some sanding and a brave push.
