About this 3D model

Well, this couldn't possibly end in tears! :D Let's use a power drill as a string winder for delicate musical instruments! What we have here is an adaptor for joining your drill chuck to your tuning pegs, so you can crank up the power, snap a string, and take someone's eye out! In all seriousness, this does seem to work well, despite it seeming like a somewhat inadvisable approach to instrument maintenance. You'll want to use a drill with variable speeds, so you can moderate the winding.
