On the third day we learned how to use Inventor. Inventor is a program were it enables you to make 2D and 3D models of parts and widgets. The pictures below show how I made widget number 6. Step one select a plane, for this I used the XY plane. For the second step I drew out the lines and then put dimensions on them. The third step was to extrude the 2D sketch 1 inch. Step number 4 was to make a rectangle and then extrude into the shape to remove material. Step 5 is to make 2 triangles at the corners an cut them out. The final step is to make a 1/4 inch hole in the middle and there is your completed widget.
I also made 5 other widgets using the same steps.
When I first put my part in maker bot it was to small I changed the scale to fit the dimensions After I rotated the widget so it would print right
During the time we used inventor I learned how to make widgets using different techniques like connecting line then dimension them. The biggest thing I learned was how to use the 3D printer and learned how it worked.
