Create a Cylinder and rotate it 90° along the Y-axis, then change its dimensions to X: 16，Y: 3，Z: 3 mm and position to X: 0，Y: 9，Z: 9. This will be used as a rotation anchor point. 
Select the Cylinder you just created and click on Clone to duplicate another Cylinder. Change this new part’s dimensions to X: 8，Y: 9，Z: 9 mm. 
Select the two Cylinders shown in the image above, click Clone, and change the parts Y-axis position to 21. 
Create a Cube and change its dimensions to X: 8，Y: 12，Z: 10 mm, and position to X: 0，Y: 15，Z: 9.5. 
Create a Cylinder and rotate it 90° along the Y-axis, change its dimensions to X: 20，Y: 23，Z: 25 mm, and position to X: 0，Y: 15，Z: 24. 
Select the Cube and click on Hole. 
Select the Cylinder and click Hole again. 
Create a Cube and change its dimensions and position as shown in the image above. Call this the Cutting part.

Inspect the you progress and you will see the Fingertip is too hollow. Because of this, we need to fill the inside of the Fingertip in. Create a Cube and change its dimensions to X: 8，Y: 13，Z: 10 mm and position to X: 0，Y: 34，Z: 8. 
Select the Cube and click Clone. Next, change the parts dimensions to X: 10，Y: 20，Z: 10 mm and position to X: 0，Y: 34，Z: 15. Call this the Cutting part.
