Step 1: Design
Create a new part file using the Standard Part template
New -> Standar Part.ipt
Draw a snowman using three circles and two rectangles. Save the sketch.
Extrude the front face 0.75in
On the back side start a sketch and use project geometry to get the outline of the snowman, then use offset to get a larger shape about 0.2in larger.
Extrude this sketch in the opposite direction of the first 0.1in this will be the handle part
On the back again project geometry and make it 0.1in smaller than the inside shape
Extrude cut this shape in the direction of the first through all, this will give us a cutter 0.1in thick
Save the part and then export it as an .STL file
