About this 3D model

I have designed a butter stick last time. After used by my wife she asked me to make some modifications. One is improving moving speed which the old one is really slow. Another is changing the rotation direction which fits the normal use.I make a much faster move speed butter stick. Now it is faster 5.25 times than the old one. And also change the rotation direction to normal. Since all parts are 3D printed, all model is simpler than the old one.The decoration patterns are the same as the old models. If you want to use them please download them at Thingiverse under my catalog.All parts printed without a support layer.Print SettingsPrinter brand: AnycubicPrinter: All-metal MegaRafts: NoSupports: NoResolution: 0.2Infill: 50%Filament_brand: Polymaker PolyflexFilament_color: WhiteFilament_material: PLA https://youtu.be/StR-TANDV48
