Spool Winder handle and crank remix

Really like the spool winder by SDHayes and the crank remix by Andrey Orlov, been using them for some time. But when there is too much resistance from the spool you are unwinding, the handle may turn around the axle, making it a little less hexagonal, making the handle turn more easily around the axle, etc… I lightly adapted the handle and the crank gear to prevent this. Other parts should be downloaded from https://www.printables.com/model/365814-improved-spool-winder-helical-gears/files (for the retension cap for the axle) and https://www.printables.com/model/223588-much-improved-spool-winder-helical-gears/files (everything else).
