In this instructable I will teach you how to make a 3D printed fidget spinner!
Open up Autodesk Inventor Professional 2017
Click on NEW to create a project and select standard(mm) in the metric folder. After you do this press create.
Press on "Start 2D Sketch" and then select the XY plane to start making your fidget spinner.
Use the circle tool to create two circles that are 22.1mm in diameter. Make sure that the circles are directly on top of each other.
Press on the dimension tool and select both dots in the middle of each circle, then make the line 32-35mm.
Create two more circles 37mm in diameter that are in the same spot as your previous circles
Create two vertical lines on each side of the circles
Select the trim tool and trim the inside of each circle.
Select the circular pattern tool and highlight all your work. Select the clicking tool and press on a dot in the middle of one of the circles. A fidget spinner with 6 sides should appear, change it to 3 sides.
Select "finish sketch" on the top right corner
Select the "extrude" tool and extrude your fidget spinner by 7mm.
Select the "fillet" tool and click on all three corners of your fidget spinner. Hold and drag to round out the fidget spinner to your liking.
Select the "fillet" tool again and select the front and back edge, set it to 2mm to round them off
