About this 3D model

I believe this is a full set of change gears for the 7 X 10 Mini lathe. Suggested material is Taulman 618 Nylon or ABS. If you're familiar with Freecad you can make any size you need by simply editing the number of teeth. For Freecad in the Combo view double click on involute gear to edit it. Then simply change the number of teeth and save it. You'll have to select the gear and export it as an STL file. SPECIFICATIONS Pressure Angle 20 Bore Diameter 12mm Face Width 8mm Key Depth 1.4mm Key Width 3mm Modules .994 (design reference) If your lathe has different measurements for bore and key post them here and I will draw them up.
