7 X 10 Mini lathe change gears (metric dimensions)

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.
